What's Wrong?

The left edge of the Claude Desktop window is cut off — approximately 30–50px of content is missing from the sidebar, main chat area, and all UI elements on the left side. The right panel (Memory/Instructions/Files) renders normally. The issue affects both the home screen and inside projects/conversations.

Environment:

• Mac: MacBook Pro 2019 (AMD Radeon Pro 5500M)
• macOS version: [please fill in]
• Claude Desktop: latest version, freshly reinstalled
• Display: custom scaled resolution (displayBounds reported as 1344×840 in window-state.json)

Started: ~April 15, 2026 (two days before report)

Persists across:

• App restarts
• macOS restarts
• Deleting com.anthropic.claudefordesktop.plist + killall cfprefsd
• Clearing GPU caches (GPUCache, DawnGraphiteCache, DawnWebGPUCache)
• Full uninstall and reinstall
• Launching with --disable-gpu flag
• Launching with --force-device-scale-factor=1 flag
• Changing display scaling back to default

Does NOT affect:

• claude.ai in browser (renders normally)
• Any other app on the system

Error Messages/Logs

Steps to Reproduce

Steps to Reproduce:

1. Open Claude Desktop on MacBook Pro 2019 (Intel, AMD Radeon Pro 5500M)
2. Observe that the left ~30–50px of all window content is clipped/missing
3. This affects the sidebar (conversation titles truncated on left), main chat area (message text truncated), and home screen (project cards truncated)
4. The right-side panel (Memory/Instructions/Files) renders correctly
5. The issue is persistent — it appears on every launch and does not resolve on its own

Note: This is not intermittent. Once it started (~April 15, 2026), it has been 100% reproducible on every launch. No specific user action triggered it — it appeared after a routine app update.

The same account viewed at claude.ai in Safari/Chrome renders correctly with no clipping.

Troubleshooting already attempted (none resolved it):

1. Restarted macOS — no change
2. Deleted ~/Library/Preferences/com.anthropic.claudefordesktop.plist + ran killall cfprefsd — no change
3. Deleted GPU caches (GPUCache, DawnGraphiteCache, DawnWebGPUCache) from ~/Library/Application Support/Claude/ — no change
4. Completely uninstalled and reinstalled Claude Desktop — no change
5. Launched with --disable-gpu flag — no change
6. Launched with --force-device-scale-factor=1 flag — no change
7. Changed display scaling from custom back to default — no change

If your mac use intel then it's a GPU issue.

You need to start Claude app and disable the GPU compositing:

Close the Claude app.
Open your terminal and enter:
/Applications/Claude.app/Contents/MacOS/Claude --disable-gpu-compositing

Now the Claude app opens with GPU compositing disabled.

Then you can create an Automator so that each time you open the app is does it automatically.

You can ask Claude on how to do it.

I had the same issue and it fixed it after doing these steps.
