Codex Desktop plugin marketplace layout is horizontally clipped on Intel Mac unless --force-device-scale-factor=1 is used

What version of Codex is running?

Codex Desktop App version: 26.506.21252

What platform is your computer?

macOS on Intel Mac (x86_64).

What issue are you seeing?

The Codex Desktop App plugin marketplace page renders incorrectly on my Intel Mac. The plugin list appears horizontally shifted/clipped: most plugin card content is cut off, with large blank/blurred areas and only the right side of plugin rows/buttons visible.

This happens consistently in the Plugins page. The plugin data appears to load, but the layout is miscomputed, so the page is hard to use.

Steps to reproduce

  1. Open Codex Desktop App on an Intel Mac.
  2. Go to the Plugins page.
  3. Observe that plugin cards/list items are horizontally clipped or shifted, so only partial text/buttons are visible.

Expected behavior

The plugin marketplace/list should render normally, with plugin names, descriptions, and install/manage buttons visible and aligned.

Actual behavior

The list is horizontally offset/clipped. Only parts of the plugin rows are visible, and large blank/blurred areas cover the main list area.

Workaround found

Launching Codex with a forced device scale factor fixes the layout:

open -na /Applications/Codex.app --args --force-device-scale-factor=1

Direct launch also works:

/Applications/Codex.app/Contents/MacOS/Codex --force-device-scale-factor=1

Using the normal Dock/Finder launch reproduces the broken layout again.

Things already tried

  • Reset app zoom with Cmd+0
  • Refresh/relaunch Codex
  • Restart the app
  • Remove/rebuild main app caches under ~/Library/Application Support/Codex/
  • Remove/rebuild the Partitions/codex-browser-app cache, code cache, GPU cache, session storage, local storage, shared storage, and blob storage
  • Remove an older /Applications/Codex-intel.app install so only /Applications/Codex.app remains

None of those fixed it. Only --force-device-scale-factor=1 fixes the display.

Additional context

This looks like an Electron/Chromium HiDPI scaling or compositor/layout issue on Intel Mac. There are existing Intel Mac rendering-related issues such as #18341, but this one affects the Plugins marketplace/list page specifically.

I can provide screenshots if needed.

I can confirm this workaround fixes the Plugins page clipping on another affected Intel Mac.

Environment:

  • Codex Desktop release observed locally: codex@26.506.21252
  • macOS 13.7.8 (22H730)
  • Architecture: x86_64
  • GPU: Intel Iris Plus Graphics 650
  • UI language: Chinese

Result:

  • open -a "Codex" --args --force_high_performance_gpu did not fix the issue on this machine.
  • Clearing render caches did not fix it.
  • Removing AppleTextDirection did not fix it.
  • Launching with this command did fix the wide-window Plugins page clipping:
open -na /Applications/Codex.app --args --force-device-scale-factor=1

Side effect:

  • The UI becomes visibly less sharp / lower clarity after forcing the device scale factor. The workaround is usable, but it trades rendering correctness for reduced visual crispness.

I can still reproduce this on a newer Codex Desktop build.

Environment:

  • Codex Desktop: 26.506.31421 (build 2620)
  • macOS: 15.7.5 (24G624)
  • Platform: Darwin 24.6.0 x86_64 i386
  • Machine: Intel Mac
  • GPU: Intel UHD Graphics 630 + AMD Radeon Pro 5500M
  • Display: built-in display, no external monitor
  • UI language: Chinese

Behavior:

  • On the Plugins page, making the Codex window fullscreen or manually resizing it wider causes a large opaque/dark block to appear across the middle of the page and cover the plugin content.
  • Manually resizing the same window narrower makes the Plugins page render normally again.
  • I have observed this for at least two weeks, and it has persisted through at least two Codex app updates.

I have not yet tested --force-device-scale-factor=1 on this machine, but the symptom matches this issue closely. Screenshot of the wide/fullscreen broken state:

Additional data point: changing the macOS display resolution/scaling also resolves the Plugins page clipping on the same affected Intel Mac.

Current observed desktop bounds after changing display settings:

0, 0, 2048, 1280

This further supports that the bug is tied to effective device scale factor / HiDPI scaling / viewport measurement rather than plugin data or cache state. The previously confirmed workaround remains:

open -na /Applications/Codex.app --args --force-device-scale-factor=1

But adjusting the system display resolution/scaling can also make the normal Codex UI render correctly without needing that launch flag.

I can reproduce the same issue on a newer Intel Mac setup.

Environment:

  • Codex App: 26.513.31313
  • Build: 2867
  • Codex CLI: 0.131.0-alpha.9
  • Platform: macOS 26.5 (25F71), Intel / x86_64
  • uname -mprs: Darwin 25.5.0 x86_64 i386

What I see:

  • The Plugins page header/sidebar renders normally.
  • The plugin marketplace/list area is horizontally clipped/shifted.
  • Plugin cards show large blank/blurred areas, and only partial plugin names/descriptions/buttons are visible.
  • The issue persists after reinstalling the latest Intel DMG.

Things tried that did not fix it:

  • Cmd+0 zoom reset
  • Refresh/relaunch/restart Codex
  • Reinstall latest Intel build from the official DMG
  • Clear/rebuild Codex render caches (Cache, Code Cache, GPUCache, DawnGraphiteCache, DawnWebGPUCache, blob_storage)
  • Launch with --disable-gpu --disable-gpu-compositing
  • Reset app-level text direction defaults

I am going to test the workaround from this issue:

open -na "/Applications/Codex.app" --args --force-device-scale-factor=1

The screenshot matches the issue description: the "Make Codex work your way" Plugins page loads data, but the plugin card/list content is clipped and shifted horizontally.

I can reproduce this on an Intel MacBook Pro with Intel graphics.

Environment:

  • MacBookPro14,1
  • Intel Core i5 / Intel Iris Plus Graphics 640
  • macOS 13.7.8
  • Codex 26.519.41501
  • Electron 42.1.0, app arch x64

Observed behavior:

  • Normal launch: opening the Plugins / Marketplace page shows a large black rendering artifact that covers the page content.
  • open -na /Applications/Codex.app --args --force-device-scale-factor=1: the black artifact disappears, but the whole UI becomes noticeably blurry, especially text rendering.
  • --disable-gpu-rasterization: black artifact still appears.
  • --force-device-scale-factor=2: black artifact still appears.
  • --disable-gpu: Codex does not open correctly on this machine.
  • --disable-gpu-compositing: black artifact disappears and text remains sharp, but the UI becomes noticeably less smooth, especially when vertically scrolling pages.

For now, --disable-gpu-compositing is the most usable temporary workaround for managing plugins, but it is not ideal as a daily launch mode because of the scrolling/UI performance hit.
