Codex Desktop plugin page renders persistent blank overlay / broken layout on Intel macOS

What version of the Codex App are you using (From “About Codex” dialog)?

Codex Desktop 26.429.30905 (2345)

What subscription do you have?

Not included.

What platform is your computer?

• macOS 26.4.1 (25E253)
• Intel Mac, x86_64
• Intel Core i7, 6 cores, 16 GB memory
• GPUs:
• Intel UHD Graphics 630, Metal supported
• AMD Radeon Pro 5300M, Metal supported

What issue are you seeing?

The Codex Desktop Plugins page consistently renders a large blank / translucent white overlay and broken layout in the center of the page. The page behind it is partially visible, but the overlay obstructs the plugin list and the hero/content area appears mis-positioned or clipped.

This happens every time the Plugins page is opened and makes the plugin surface difficult to use.

What steps can reproduce the bug?

1. Open Codex Desktop on macOS.
2. Open the Plugins page from the sidebar.
3. Observe the large blank white / translucent overlay in the middle of the page.
4. Switch between Plugins and Skills, restart the app, or reopen the Plugins page.
5. The same broken overlay/layout remains.

What is the expected behavior?

The Plugins page should render normally, without a blank overlay, and the plugin list / hero content should be visible and clickable.

What troubleshooting has already been tried?

The issue persists after:

• Pressing Esc
• Clicking and clearing the plugin search box
• Switching between Plugins and Skills tabs
• Fully quitting and reopening Codex
• Reinstalling / restarting the app flow
• Deleting Electron cache folders:
• Cache
• Code Cache
• GPUCache
• DawnCache
• Renaming / resetting ~/Library/Application Support/Codex
• Toggling macOS display transparency / motion accessibility settings
• Testing GPU behavior:
• Automatic graphics switching was originally enabled (gpuswitch = 2)
• Disabling automatic graphics switching made the overall system feel more responsive and activated the AMD Radeon GPU
• The Plugins page rendering bug still persisted
• Attempting to launch Codex with:
• open -a Codex --args --disable-gpu --disable-gpu-compositing
• This made Codex unresponsive on this machine, so it was not a usable workaround

Additional observations

• WindowServer CPU usage is often around 30% for extended periods.
• GPU History originally showed activity mainly on Intel UHD Graphics 630; after disabling automatic graphics switching, AMD Radeon Pro 5300M showed activity and the system felt visually faster.
• The Plugins page bug remained unchanged even when the AMD GPU was active.
• This looks related to a Codex Desktop web rendering/layout issue rather than the system lacking GPU acceleration.
