Description

Windows GUI launches to pure white screen while CLI works normally

Summary

On Windows, the OpenCode desktop GUI consistently opens to a pure white screen, while the CLI works normally.

I have already tried:

• full uninstall
• deleting all local app data / cache
• reinstalling
• disabling GPU
• disabling software rasterizer

None of these fixed the GUI white screen.

The CLI remains usable.

Environment

• OS: Windows
• OpenCode version: 1.14.21
• GUI executable:
  • D:\OpenCode\OpenCode.exe
• CLI executable:
  • D:\OpenCode\opencode-cli.exe

After reinstall, another mirrored install path also appears:

• D:\opencode\OpenCode.exe
• D:\opencode\opencode-cli.exe

GPU environment

• NVIDIA GeForce RTX 2060
• Intel UHD Graphics 630

WebView-related local data

The app recreates local data under:

• %APPDATA%\OpenCode\EBWebView
• %LOCALAPPDATA%\ai.opencode.desktop

Actual behavior

• Launching the desktop GUI results in a pure white window
• The app process remains running
• The sidecar starts successfully
• No useful frontend error appears in the app log
• The CLI works normally

Expected behavior

The GUI should render normally instead of showing a blank white screen.

Reproduction steps

1. Install OpenCode on Windows
2. Launch the desktop GUI
3. The window opens but remains completely white
4. CLI still works as expected
