Electron 38 has built-in Wayland auto-detection. Even without ELECTRON_OZONE_PLATFORM_HINT, it detects WAYLAND_DISPLAY and tries to use Wayland, triggering the empty window bug in Signal Desktop. Explicitly force X11/XWayland mode with --ozone-platform=x11 flag to prevent auto-detection and fix the empty window issue. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
