Summary

Codex Desktop renders with an incorrect global scale/layout on an Intel Mac. The main screen and the Plugins page are oversized and clipped, making parts of the UI unusable.

Environment

  • App: Codex Desktop
  • Codex version: 26.519.31651 (CFBundleVersion 3017)
  • macOS: 15.7.7 (24G720)
  • Architecture: x86_64
  • CPU: Intel(R) Core(TM) i5-8257U CPU @ 1.40GHz
  • Install path: /Applications/Codex.app

What happens

  • Main screen content appears much larger than expected and lower content is clipped/faded out.
  • Plugins page renders with severe horizontal clipping/offset. Large blank areas appear and cards/content are partially offscreen.
  • The issue appears global, not limited to one page.

Expected behavior

Codex Desktop should render at the normal scale and fit within the app window on Intel Mac.

Workarounds attempted

None of the following resolved the issue:

  • Cleared Codex rendering caches:
  • ~/Library/Application Support/Codex/GPUCache
  • ~/Library/Application Support/Codex/DawnGraphiteCache
  • ~/Library/Application Support/Codex/DawnWebGPUCache
  • ~/Library/Application Support/Codex/Cache
  • ~/Library/Application Support/Codex/Code Cache
  • Started Codex with GPU disabled:
  • open -n /Applications/Codex.app --args --disable-gpu
  • Started Codex with explicit device scale factor:
  • --force-device-scale-factor=1
  • --force-device-scale-factor=0.75
  • --force-device-scale-factor=0.5
  • Tried GPU compositing disabled:
  • --disable-gpu-compositing
  • Reset app-specific macOS text-direction/window preferences:
  • AppleTextDirection
  • NSForceRightToLeftWritingDirection
  • window frame preference entries
  • Restarted Codex after the above attempts.

Notes

This looks like an Electron/WebView rendering or scaling issue specific to Intel Mac / HiDPI handling. Screenshots show the main composer and Plugins page both oversized/clipped.

Additional screenshot details from the affected machine:

  1. Plugins page: the top Plugins / Skills tabs are visible, but the page body is horizontally offset/clipped. The search bar starts around the middle of the window, the hero carousel/card is partially offscreen to the right, and large blank regions appear where plugin content should be.
  1. Main/home screen: the prompt composer appears oversized and clipped. The lower half of the composer fades/cuts off, and the page content below is mostly blank/washed out. This confirms the issue is global UI scaling/layout, not isolated to the Plugins page.

The screenshots show the same Codex Desktop UI rendering at an incorrect scale/position on macOS Intel (x86_64).
