Bug
The Codex Desktop “Plugins” page renders with a large black overlay/glitch that covers the plugin cards and makes the page mostly unusable.
Environment
- Codex Desktop: 26.429.30905
- Build: 2345
- Electron: 41.2.0
- macOS: 26.4.1
- Mac: MacBookPro16,1
- CPU: Intel Core i9
- GPU: Intel UHD Graphics 630 + AMD Radeon Pro 5500M
- UI language: French
What I tried
- Reset macOS, issue still present
- Removed Codex caches:
- GPUCache
- DawnGraphiteCache
- DawnWebGPUCache
- Cache
- Reinstalled Codex from the official DMG
- Disabled automatic graphics switching
- Launched from
/Applications/Codex.app - Removed quarantine attribute
None of these fixed the issue.
Expected
The Plugins page should render normally.
Actual
A large black rectangle/overlay appears over the page, hiding much of the UI. The rest of Codex appears usable, but the Modules d'extension / Plugins page is visually broken.
Screenshot
I can provide screenshots showing the overlay if needed.

Additional screenshot context: the visual glitch appears on the Plugins page in French UI. It shows a large black overlay covering the center-left of the plugins content area, plus a smaller black rectangular artifact over the hero carousel area. The underlying hero/card content is partially visible on the right, while plugin list rows below are clipped/partially hidden. The left sidebar remains rendered normally, which makes this look isolated to the Plugins page content/hero compositing rather than a whole-window render failure.
“Electron may have compatibility issues with Intel integrated graphics on Intel-based MacBooks, which can lead to rendering glitches or performance problems.
On macOS, you can force the application to use the discrete GPU to work around this issue. For example:
open -a "Codex" --args --force_high_performance_gpu
Most Chrome/Electron-based applications can be launched this way, which helps avoid rendering errors or lag caused by Intel integrated graphics.”
