🐛 Font & Emoji Rendering: Windows Strikes Again

Some users (including us) experienced a bizarre issue: top-right emoji buttons appeared as blank white squares or even froze the app on startup, even though emoji rendered perfectly elsewhere in the app and system.

After a marathon troubleshooting session, we discovered that system font corruption, driver updates, or Windows font cache issues can cause WinForms buttons using emoji (via Segoe UI Emoji) to break unpredictably.

What We Changed:

  • Added new code to render emoji as bitmaps on buttons, sidestepping font fallback bugs.
  • If emoji rendering fails, the button now displays a fallback icon or simple label so you’re never left with a useless white square.
  • Added a troubleshooting tip in the docs: if emoji disappear or buttons go blank, try clearing the font cache, repairing .NET, or switching to a simple symbol.

⚙️ Internal Robustness Improvements

  • Improved button creation so all icons (emoji or otherwise) always fall back gracefully, with or without event handlers.
  • Refactored top-right button logic: ensured every button is added to the form reliably, with unique coordinates and click handlers.
  • Startup is now resilient to font, GPU, and system oddities: buttons never silently vanish, even if something else breaks.

📝 Behind the Scenes: What Went Wrong?

  • System font glitches or driver updates can break GDI+ emoji painting—WinForms just draws a white box instead of failing gracefully.
  • Unhandled exceptions in button setup could leave you with missing or non-responsive controls—fixed with stricter exception handling and debug logs.
  • If you run into this, see the new troubleshooting tips!
