Windows desktop sidebar text overlaps after launch

### What happened?

After updating/launching Codex Desktop on Windows, the left sidebar renders with incorrect row heights. Text in the sidebar overlaps vertically while the main chat area renders normally.

The problem persists after restarting Codex and after clearing/recreating the main Chromium cache folders.

Screenshot

A screenshot was captured from the affected machine. see head

Environment

• OS: Windows 10 Pro, version 2009, 64-bit
• OS HAL/build info: 10.0.19041.6456
• Codex Desktop package: OpenAI.Codex_26.527.7698.0_x64__2p2nqsd0c76g0
• Codex Desktop version: 26.527.7698.0
• Install location: C:\Program Files\WindowsApps\OpenAI.Codex_26.527.7698.0_x64__2p2nqsd0c76g0
• Applied DPI from registry: 120 (HKCU\Control Panel\Desktop\WindowMetrics\AppliedDPI)
• HKCU\Control Panel\Desktop\Win8DpiScaling: 0
• User reports Windows system settings were not changed before the regression.

Steps to reproduce

1. Launch Codex Desktop on Windows.
2. Open the main Codex Desktop window with the left sidebar visible.
3. Observe the sidebar thread/workspace list.

Expected behavior

Sidebar list items should have sufficient row height and text should not overlap.

Actual behavior

Sidebar entries overlap vertically. Some section headers and thread titles are drawn on top of adjacent text. The center chat view still appears usable.

Troubleshooting already attempted

• Restarted Codex Desktop.
• Verified multiple Codex.exe processes were running and restarted the app.
• Renamed/recreated these cache folders under %APPDATA%\Codex:
• Cache
• Code Cache
• GPUCache
• DawnGraphiteCache
• DawnWebGPUCache
• blob_storage
• The rendering issue persisted after relaunch.

Relevant local diagnostics

Recent logs show normal startup plus unrelated-looking errors/warnings, but no obvious layout error:

warning [remote-connections/window-context] refresh_local_remote_control_client_id_failed errorMessage="Sign in to ChatGPT in Codex Desktop to check remote control authorization."
error [wsl] error retrieving eligible distro error="Error: Command failed: wsl.exe --status"
error [electron-message-handler] Request failed ... method=fs/readFile ... message="系统找不到指定的路径。 (os error 3)"
info [electron-message-handler] [startup][renderer] app routes mounted after 35025ms

Chromium profile preference contained:

profile.exit_type = "Crashed"
extensions.last_chrome_version = "148.0.7778.179"

Notes

I searched existing issues for sidebar text overlap row height, Windows text overlap sidebar, and Codex Desktop sidebar rendering overlap. I found related app/browser/compositor and UI scale issues, but not this exact left-sidebar row-height/text-overlap failure.
