Environment
- Windows 11

Problem
Zotero becomes unresponsive after approximately 5-30 minutes.
Sometimes a PDF is open when the issue occurs, but the same problem also occurs when no PDF is open.
The window becomes white/greyed out and Windows reports that Zotero is not responding.
Troubleshooting performed
- Updated to the latest Zotero version
- Disabled all plugins
- Reproduced with a completely fresh profile
- Reproduced with multiple PDFs
- Reproduced even without PDFs open
- WebDAV manual sync works normally
- Set layers.acceleration.disabled=true
- This appeared to improve the situation temporarily
- However the problem still occurs

Debug output

The problem is specifically related to the spacedesk Graphics Adapter.
When Win32_VideoController shows:
Intel(R) UHD Graphics
DisplayLink USB Device
Zotero remains stable.
When spacedesk Graphics Adapter is present, Zotero freezes again.
The issue occurs even with:
- a fresh Zotero profile
- all plugins disabled
- no PDF open
