If the scroll-edge fade shader failed to compile or link, the init path
left its ready flag clear and tried again on the very next frame. On a
driver that rejects the shader that meant a fresh compile attempt every
frame, for the life of the program.
- A failed init is now latched and treated as final until destroy(), so
the compile is attempted once, the failure is logged once, and the
fades stay disabled without further retries. Destroying the shader
clears the latch so a later re-init can try again.

The acrylic effect blits its backdrop from the default framebuffer using
the logical viewport size as the source rectangle. On a HiDPI display
the framebuffer is larger than the logical size, so the blur sampled
only the lower-left corner of the screen and the glass showed the wrong
region stretched across each panel.
- The capture blit source now uses the real framebuffer pixel size
(logical size times ImGui's DisplayFramebufferScale, truncated the
same way the GL backend does), while the capture and blur targets stay
at logical size. The framebuffer size is tracked separately from the
viewport size so quality or buffer-lifetime resets cannot lose it, and
moving the window between a Retina and a non-Retina display redoes the
capture. DX11 is unaffected; its scale is one.
- The debug screenshot sweep captures at framebuffer size too, so HiDPI
captures are no longer cropped.
Tests: the framebuffer-extent helper matches the GL backend's
truncation and falls back to the logical size when the scale is unknown.

The acrylic material carried a full composite shader — vertex and
fragment source, compile and link helpers, the program handle and seven
uniform locations — that nothing ever invoked. The acrylic is composited
on the ImGui draw list, not through this program.
- Remove the dead shader source, its compile/link helpers, the program
and uniform fields, and the compile/link/cleanup steps in init and
shutdown. No behaviour change; init no longer builds a program that is
never bound.

Glass cards scrolled out of view still ran their full effect path, and
the rainbow border always used a segment count derived from a fixed
per-pixel budget, so wide cards drew far more line segments than their
slowly changing gradient needed.
- A glass panel whose rectangle lies wholly outside the draw list's clip
rect now returns early, so a scrolled-out card draws nothing (its
border and ember passes are skipped along with the fill).
- The rainbow border is split into segments by perimeter arc length:
straight edges get one segment per ~32 dp, corner arcs get a few
chords each to stay round, and a fully transparent border is skipped
outright. A wide card now draws tens of segments instead of a couple
hundred, with no visible change.
Tests: the segment fractions are ascending and bounded, each corner arc
keeps at least three chords, and the rect-cull margin test.

The theme effects stored their animation time in a 32-bit float taken
from the ImGui clock. After a few days of uptime a float can no longer
resolve a single frame step, so every oscillation, drift and sweep began
to stutter, snapping forward a frame at a time instead of moving
smoothly.
- The clock is now held as a double, and the phase/oscillator maths runs
through a small set of shared helpers that reduce the argument in
double before returning a float. A float clock at 30 days steps by a
quarter second per ULP; the double clock stays frame-accurate.
- Hue cycling, the rainbow and gradient borders, shimmer, specular
glare, glow pulse, edge trace, embers, the sandstorm and the viewport
wash all use the shared helpers, so their timing no longer drifts with
uptime.
Tests: the helpers advance smoothly after seven days, pin the legacy
float breakdown at 30 days, and stay in range for negative offsets.

Turning blur off (blur 0), switching to low-spec mode or enabling
reduced transparency after the acrylic targets existed left the capture
FBO and both blur ping-pong targets allocated for the rest of the
session, although nothing draws with them while the effect is skipped.
They are now released at a frame boundary and rebuilt on demand:
- ImGuiAcrylic::ReleaseIdleBuffers() runs right after app.preFrame(),
before NewFrame(), when the previous frame's draw data has been
rendered, and once in the resize-watcher frame (GL and DX11). While
the effect is skipped it frees the targets; when the effect is wanted
again it reallocates them once, with no per-frame retry if that fails;
- resize() while skipped only records that a reallocation is needed;
- the release checks the GL names (and each DX11 texture) directly, so a
half-allocated ping-pong pair is freed too; DX11 also resets the
ping-pong index;
- the capture paths and applyBlur() return early without a capture
buffer, which would otherwise blit the default framebuffer onto
itself;
- each release logs "released targets (effect skipped)".
With blur on, the path and the output are unchanged (screenshot sweeps
within noise). After re-enabling, the first frame draws the tinted
fallback until a fresh capture exists.
Measured with software GL, toggling every 30 frames for 1200 frames: the
targets were released exactly one frame after each switch-off (22 of 22)
and rebuilt on each switch-on (21 of 21), with no GL or framebuffer
errors. While off at 1280x720, with a fixed malloc mmap threshold, the
process holds 4.62 MB less (the 1280x720 RGBA8 capture plus two 320x180
RGBA16F blur targets) and RssAnon is about 3.1-3.5 MB lower. With
glibc's default threshold the freed memory stays in the heap and RssAnon
does not visibly drop.
Known issue: every off/on pair now frees and reallocates those targets.
Under software GL (llvmpipe) with the default glibc allocator the freed
texture memory is not reused: toggling every 2 frames grew RssAnon from
49 to 906 MB over 240 pairs, every 8 frames from 56 to 179 MB, and every
30 frames it levels off near 120 MB. It is not a GL object leak (with a
fixed mmap threshold the mapped bytes stay flat), and on a hardware
driver (WSLg d3d12) RssAnon stayed between 67.5 and 74.9 MB under the
2-frame churn (94.3 MB without the release). Users reach fast toggling
by holding Ctrl+Shift+Down (key repeat, about 20 Hz) or by dragging the
blur slider back and forth across 0. A short delay before releasing
would avoid it if software-rendered users matter.
Not verifiable here: the DX11 release and reallocation at runtime, and
macOS.

The GL window asked for a 24-bit depth and 8-bit stencil buffer, and
every acrylic Framebuffer attached a DEPTH24_STENCIL8 renderbuffer the
size of its color texture. Nothing uses them: no code enables depth or
stencil tests (the ImGui GL3 backend disables both), every blit and
readback is color-only, and only Framebuffer::clear() also cleared the
depth buffer, which nothing read. The window and every FBO, including
the full-size capture FBO, carried that memory, and the FBO
renderbuffers were reallocated on every resize.
Now:
- the window requests depth 0 and stencil 0 explicitly (SDL3 requests a
depth buffer by default when the attributes are simply removed);
alpha 8 stays for the transparent window;
- Framebuffer has no renderbuffer, and clear() clears color only;
- a permanent startup log line,
"GL default framebuffer: depth=N stencil=N", reports what the driver
provided; "(no attachment)" marks a failed query, which is how some
drivers report a buffer that does not exist.
The log shows depth=0 stencil=0 both offscreen and on WSLg X11, where
"Window transparency enabled by compositor" is still logged, with no
framebuffer-incomplete errors. Screenshot sweeps at 1280x720 and
2560x1440, and a glass run with ui_opacity 0.6 and blur on (so panels go
through the FBO blur), match the previous build within noise. The
driver-side memory saving itself was not measured. DX11 is unaffected:
its swap chain has no depth buffer.
Not verifiable here: macOS (an NSOpenGL 3.2 core context with a
transparent window).

While theme effects were on (the default) the main loop drew every
frame it could. Where vsync is off (offscreen, some drivers, remote
sessions) an idle wallet spun at ~3,000 fps, 88% of a core; with vsync
it still drew every refresh. Frames are now paced by what needs them:
- full rate while there is input, a held key, a window appearing or
settling, a smooth scroll or the UI sweep;
- ambient (30 fps focused, 10 fps unfocused) for theme effects, the
acrylic backdrop, avatar animations and notifications;
- progress (10 fps focused, 4 fps unfocused) for UI that changes
without input. The updater and bootstrap downloads, console
commands, lite-wallet operations, seed migration, the loading
overlay and the lock-screen countdowns ask for it with
material::RequestProgressFrame();
- otherwise idle, as before: wait for events, with a housekeeping wake
every 2 s (5 s unfocused).
A software frame cap (0.9x the display refresh) bounds the loop where
vsync is off, and hidden, occluded or minimized windows get no ambient
frames. Reduce Motion freezes the theme-effect clock
(ThemeEffects::setMotionFrozen), so it needs no ambient frames either.
The displayed-balance roll goes through one clamped StepDisplayLerp
(balance_lerp.h). An idle-length frame pushed dt*speed past 1, so the
roll overshot, and under Reduce Motion's speed of 999 it diverged to
inf/NaN. The classic layout had its own copy of the old code.
Idle CPU, Lite build, offscreen (no vsync): 88% -> 5% of a core with
effects on, and 91% -> 3% with effects saved off (with the previous
commit).

Low-spec mode, theme effects, blur, UI and noise opacity and the
console scanline reached the live effects state only once the Settings
page or the first-run wizard was opened. "Effects off" and low-spec
therefore reverted at every launch, and the animated defaults kept the
main loop busy (91% of a core on an idle Lite wallet whose effects were
saved off).
- App::applyVisualSettings(): one low-spec-aware path from the saved
prefs to the effects state, used at startup (after the skin, since
setActiveSkin reloads the effect config), by the low-spec hotkey, the
wizard and the Settings page.
- Low-spec stays a runtime-only override. The Settings page shows the
overrides but persists the real prefs from its snapshot, and opening
it under low-spec no longer turns theme effects and blur back on.
Unticking a low-spec in the wizard that was loaded rather than ticked
there now restores the saved prefs.
- Theme effects on/off always pairs with reduced transparency (the
rainbow, shimmer and glare layers), as at startup and in the hotkeys.
- kAcrylicMaxBlur moves to imgui_acrylic.h, so startup clamps blur
values saved in the old 0-4 range the way the slider does.

Bundles the session's UI work (the touched files carry several of these
changes together, so they are committed as one coherent UI batch):
- FAQ: new RenderFaqDialog + data-driven faq_content, opened from a
status-bar "?" (and the Windows title bar), styled like the Wallets
modal with search, Wallet/Daemon tabs, and smooth scroll.
- DPI/font-scale audit: multiply hand-drawn absolute geometry by
Layout::dpiScale() across ~30 files so nothing renders native-size at
HiDPI / font_scale 1.5 (verified with a full sweep at 1.5x).
- Mining: chart now fills the horizontal space; thread stepper +/- buttons
match the input-box height; move the stratum-host toggle into
Node & Security (v1.3.0+).
- Settings: fix the auto-shield status text overlapping the grid.
- Sidebar: drop the peer-count badge on the Network button.
- i18n: wrap 193 hardcoded literals with TR() (keys/translations added in
the preceding i18n commit), so the security/PIN/lock flow, seed-backup
wizard, and witness-rebuild dialog localize.

Jade's edge-trace hero hand-walked the panel perimeter as straight line
segments, so rounded corners chamfered into flat polygons. Retire it in
favour of the gradient-border effect, which draws via AddRect and hugs
the real corner arcs.
- theme_effects: drawGradientBorderShift gains phaseOffset + alphaMul;
drawPanelEffects now draws it on every glass panel (position-phased so
panels drift like veins at different depths, 0.6x alpha vs the active
nav button), gated behind a new opt-in gradient-border-panels flag so
button-only themes (Obsidian) are unaffected.
- jade.toml: edge-trace off; gradient-border-panels on, speed 0.10,
jade->gold; jade motes + viewport wash/vignette kept.

The modal backdrop blur was params.blurRadius (96) scaled by the user's global
acrylic blur-strength slider (blurRadiusMultiplier), so lowering the slider also
weakened every modal's backdrop. Make the modal blur a fixed hardcoded value.
Add AcrylicParams::absoluteBlurRadius: when set, applyBlur() uses the radius
as-is and skips the multiplier (threaded through both the GL and DX11 blur paths
+ the no-op stub). DrawFullWindowBlurBackdrop sets it, so the modal backdrop is
always a 96px blur regardless of the slider. Panels/other acrylic still scale
with the slider as before.
Verified: rendering a modal at blur_multiplier 0.1 vs 2.0 now produces an
identical backdrop (max pixel diff 1/255) — previously those were ~9.6px vs
~192px of blur.

The per-panel acrylic composite drew the blurred capture at
`fallbackColor.w * uiOpacity` alpha. At a lowered UI opacity that's ~24%, so the
SHARP background bled straight through the panels — the acrylic slider changed
almost nothing (measured: blur 0% vs 100% differed in 0.33% of pixels, and the
marbled background was equally crisp at both).
Draw the blurred capture at (near) full strength so it actually FROSTS the panel
(the blurred background replaces the sharp one); UI opacity now scales only the
tint overlay in DrawGlassPanel, which is the correct acrylic model — opacity =
tint, not sharp-vs-blur. Fixed symmetrically in both the GL and DX11 drawRect
paths. Verified on GL: blur 0% now shows a sharp background, 100% a smooth
frosted wash (0.33% -> 8.3% pixels changed), and the default (high-opacity) card
look is unchanged.

The acrylic system only blurred a frozen snapshot of the static app background. Add
an overlay-time re-capture so the Manage-portfolio modal blurs the LIVE tab content
behind it.
- AcrylicMaterial::captureLiveFramebuffer() (GL blit of FB 0 / DX11 CopyResource of the
backbuffer + no-backend stub) mirrors captureBackgroundDirect but bypasses the
dirtyFrames_ gate so it refreshes every frame the overlay is open, forcing a re-blur.
- ImGuiAcrylic::GetLiveCaptureCallback() returns a draw callback for it.
- market_tab: the modal inserts that callback (+ ImDrawCallback_ResetRenderState) at the
START of its overlay draw list, before the backdrop, so the capture holds the app UI
drawn below and the backdrop blurs it. On close, InvalidateCapture() re-captures the
background so other glass panels don't keep blurring the stale live capture.
- Panel theme-effects are suppressed during the market render while the modal is open
(their foreground-draw-list borders draw above all windows and would otherwise bleed
over the overlay). Market tab body is rendered again (no longer skipped).
- Backdrop draws the acrylic at full strength (fallbackColor.w=1) over an opaque base so
the blurred content reads clearly; lighter dim.
Design mapped via an Explore investigation of the capture/blur pipeline; compiles on
both OpenGL (Linux) and DX11 (Windows cross-build). Needs on-device visual verification.

Six behavior-preserving consolidations from the audit:
- RPCClient::call() overloads share a private performCall() (payload dump +
curl_easy_perform + http code) and a static parseRpcResult() (error->RpcError
extraction). The timeout overload restores the prior timeout in both the
success and catch paths, exactly as before.
- The six UnifiedCallback methods delegate to one splitUnified() that builds
the (Callback, ErrorCallback) pair once (null-check preserved).
- One liteTrimCopy() in lite_connection_service replaces 5 file-local
trim-copy helpers across the lite slice.
- lite_wallet_controller's inline height JSON parse now routes through the
tested parseLiteHeightResponse().
- theme_effects.cpp: unpackRGB()/scaledAlpha() replace 14 RGB-unpack + 5
alpha-scale copy-paste blocks.
- settings.cpp load() uses loadScalar()/loadClamped() helpers for ~44 scalar
fields. Besides removing boilerplate this HARDENS loading: ~44 fields that
previously only checked contains() now also verify the JSON type, so a
malformed value in settings.json falls back to the default instead of
throwing/misreading. Custom cases (enum parses, legacy migrations, arrays)
stay inline; save() is unchanged.
Full-node + Lite build clean; ctest 1/1; hygiene clean.

Three P1 structural refactors from the audit; no behavior change.
1. Extract the ~180-line daemon-stdout rescan/witness parser out of the
~790-line App::update() into a pure, static, unit-testable
NetworkRefreshService::parseDaemonRescanOutput() returning a
DaemonRescanScan result struct (sits next to the existing static parse*
siblings). The scanning half moved verbatim; App::update() keeps the
state-application half, now reading scan.* fields. Adds
testParseDaemonRescanOutput() covering all six daemon signals + edge
cases against fixture log snippets — previously untestable without a
live daemon.
2. Extract the ~95-line global keyboard-shortcut block (Ctrl+, / theme
cycle / F5 / low-spec / effects / gradient / wizard) out of
App::update() into App::handleGlobalShortcuts().
3. Collapse the ImGuiAcrylic frontend fork: the GLAD and DX11 namespaces
were ~375 lines of semantically-identical code (the frontend makes zero
direct GL/DX calls — all backend work delegates to AcrylicMaterial, which
has a backend per API). Extended the single frontend's guard to
#if defined(DRAGONX_HAS_GLAD) || defined(DRAGONX_USE_DX11) and deleted the
DX11 duplicate, leaving the no-backend stub. Kills the Windows/DX11 drift
hazard (acrylic frontend changes now made once).
Verified: full-node + Lite build clean; ctest 1/1 (incl. the new parser
tests); source-hygiene clean; and the collapsed acrylic path was
compile-verified under DX11 via the mingw-w64 Windows cross-build
(ObsidianDragon.exe links).

Both are header-only, in no CMake target, #included nowhere, and their only
symbols (ScrollFadeRT, DrawScrollFadeMask) are referenced nowhere:
- src/ui/effects/scroll_fade_fbo.h — superseded by the shader-based
scroll_fade_shader.h (the implementation actually used by settings_page).
- src/ui/material/gpu_mask.h — a GPU blend-mask helper never integrated.
App + test build clean after removal; tests pass; hygiene clean.
