DanSandClaude Opus 5.5 b50d5ac31f perf(startup): build the font atlas once at the final ui.toml sizes
main() built the font atlas before App::init() loaded ui.toml, so the
first build used the hard-coded fallback sizes (H1 24 px, Body2 12 px).
App::init() then rebuilt for a saved font scale above 1.0, still before
the schema load and so still at the fallback sizes. Only the color-emoji
rebuild requested for the first frame reached the ui.toml sizes, so
color-emoji users built the atlas twice at font scale 1.0 and three
times at 1.5.

Users with chat_emoji_color=false never got that last rebuild. They
built the atlas once or twice and ran the whole session at the fallback
sizes, e.g. Body2 at 12 px instead of 15 and H1 at 24 px instead of 20.

Now:
- App::loadBaseUiSchema(), the ui.toml load moved out of App::init()
  unchanged, runs in main() before both InitImGui paths (DX11 and GL),
  together with the saved font scale and emoji style from the early
  settings read. It is idempotent, so the call left in App::init() is a
  no-op;
- the two rebuild triggers in App::init() are gone;
- Typography records what the atlas was built from (the 15 schema sizes,
  the schema's font scale, the effective emoji style and the schema
  generation), and preFrame() rebuilds once when they differ. While the
  schema generation and the emoji style are unchanged this costs two
  compares per frame.

Measured on the Lite build (color and mono emoji, font scale 1.0 and
1.5, English and Japanese): every run builds the atlas exactly once, at
the ui.toml sizes times the scale (H1 20 px and Body2 15 px at 1.0,
30 px and 22 px at 1.5), and ui.toml is loaded before the window and GL
context are created. The packaged Lite zip and AppImage log one atlas
build instead of two. Color-emoji screenshot sweeps match the previous
build within noise.

Visible changes:
- users with chat_emoji_color=false had been rendering the whole UI at
  the fallback font sizes; they now get the designed ui.toml sizes, so
  every mono-emoji screen differs from before and matches the
  color-emoji layout;
- a user skin whose [fonts] differ from ui.toml now rebuilds the atlas
  once when it is activated or left; on a runtime switch the atlas used
  to keep the old sizes until a restart. With a test skin that sets
  Body2 to 18 px, startup builds twice and ends at 18 px; switching to a
  bundled skin rebuilds once, switching among the 9 bundled skins
  rebuilds nothing (they carry an identical copy of [fonts]), and
  switching back rebuilds once;
- editing ui.toml while running still gives exactly one rebuild.

Not verifiable here: the Windows DX11 path with the schema loaded before
its first FreeType build, macOS, and the interactive font-scale slider,
Alt+scroll and emoji toggle, which were checked by reading the code.

Building

Quick Setup

The setup script detects your OS, installs all build dependencies, and validates your environment:

./setup.sh              # Install core build deps (interactive)
./setup.sh --check      # Just report what's missing
./setup.sh --all        # Core + Windows/macOS cross-compile + Sapling params
./setup.sh --win        # Also install mingw-w64 + libsodium-win

Manual Prerequisites

Click to expand manual install commands

Linux (Ubuntu/Debian):

sudo apt install build-essential cmake git pkg-config
sudo apt install libgl1-mesa-dev libx11-dev libxcursor-dev libxrandr-dev libxinerama-dev libxi-dev
sudo apt install libsodium-dev libcurl4-openssl-dev

Linux (Arch):

sudo pacman -S base-devel cmake git pkg-config mesa libx11 libxcursor libxrandr libxinerama libxi libsodium curl

macOS:

xcode-select --install
brew install cmake

Windows:

  • Visual Studio 2019+ with C++ workload
  • CMake 3.20+

Binaries

Download linux and windows binaries of latest releases and place in binary directories:

DragonX daemon (https://git.dragonx.is/DragonX/dragonx):

  • prebuilt-binaries/dragonxd-linux/
  • prebuilt-binaries/dragonxd-win/
  • prebuilt-binaries/dragonxd-mac/

DRG-XMRig fork (https://git.dragonx.is/DragonX/drg-xmrig):

Build Steps

### Clone repository (if not already)
git clone https://git.dragonx.is/dragonx/ObsidianDragon.git
cd ObsidianDragon/

Windows Build

./build.sh --win-release

Release Build

./build.sh --linux-release    # Linux release + AppImage
./build.sh --win-release      # Windows cross-compile
./build.sh --mac-release      # macOS .app bundle + DMG
./build.sh --clean --linux-release  # Clean + Release

Running

  1. Start dragonxd (if not using embedded daemon):

    dragonxd -daemon
    
  2. Run the wallet:

    cd build/bin
    ./ObsidianDragon
    

The wallet will automatically connect to the daemon using credentials from ~/.hush/DRAGONX/DRAGONX.conf.

Using Custom Node Binaries

The wallet checks its own directory first when looking for DragonX node binaries. This means you can test new or different branch builds of hush-arrakis-chain/hushd without waiting for a new wallet release:

  1. Build or download the node binaries you want to test
  2. Place them in the same directory as the wallet executable (e.g. build/bin/)
  3. Launch the wallet — it will use the local binaries instead of the bundled ones

Search order:

  1. Wallet executable directory (highest priority)
  2. Embedded/extracted daemon (app data directory)
  3. System-wide locations (/usr/local/bin, ~/dragonx/src, etc.)

This is useful for testing new branches or hotfixes to the node software before they are bundled into a wallet release.

Configuration

Configuration is stored in ~/.hush/DRAGONX/DRAGONX.conf:

rpcuser=your_rpc_user
rpcpassword=your_rpc_password
rpcport=21769
