codex - 💡(How to fix) Fix Codex Desktop UI rendering/clipping issue on Intel Mac x86_64

Summary

Codex Desktop on Intel Mac shows broken or clipped UI rendering on the home page and especially on the Plugins page. The UI elements appear to exist, but parts of cards, images, labels, and layout regions are incorrectly clipped, shifted, or only partially drawn.

Environment

• Device architecture: Intel Mac, x86_64
• macOS version: 15.7.7
• Codex Desktop architecture: x86_64
• Codex Desktop version: 26.513.20950
• Codex bundle version: 2816
• Locale/UI language: Chinese
• Date observed: 2026-05-16

Steps to Reproduce

1. Launch Codex Desktop on an Intel Mac.
2. Open the Codex home page.
3. Navigate to the Plugins page.
4. Observe the layout and card rendering.

Expected Behavior

• The home page prompt box and controls should render normally.
• The Plugins page should show complete plugin cards, images, text, search controls, and action buttons without clipping or horizontal/vertical misalignment.

Actual Behavior

• The home page mostly renders, but the prompt box/control layout appears visually off.
• The Plugins page has obvious rendering corruption:
  • Plugin card content is partially missing or clipped.
  • Large blank regions appear where content should be.
  • Card imagery and text appear shifted or cropped.
  • Carousel/card controls appear detached or misaligned.
  • Some plugin text is only partially visible.

Notes

This looks more like a Chromium/Electron rendering, GPU compositing, WebGPU, or layout clipping issue than a plugin data issue. The issue is more visible on the Plugins page, likely because that page uses heavier UI composition such as images, rounded clipping, card layouts, transforms, animation, or layered rendering.

Relevant local cache directories exist:

• ~/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

No abnormal zoom setting was found in the app preferences during local inspection.

Possible Workarounds Tried or Suggested

• Restart Codex Desktop.
• Reset zoom with Command + 0.
• Resize the app window to force a relayout.
• Clear GPU/WebGPU/rendering caches, then relaunch Codex.
• Update Codex Desktop when a newer build is available.

Impact

The Plugins page is difficult or impossible to use reliably because plugin cards and controls are not rendered correctly.
