What's Wrong?

Environment

• Platform: Claude Desktop (Windows)
• Claude Desktop version: Latest
• Operating System: Windows 11 25H2
• Hardware: Framework Laptop with external monitor

Bug Description

After Windows Hibernate (not sleep, specifically hibernate), Claude Desktop shows only a white/blank screen. The window opens but no content renders. This happens 100% of the time when:

1. Claude Desktop is running
2. External monitor is connected
3. System enters Hibernate
4. System resumes from Hibernate

Steps to Reproduce

1. Connect external monitor to laptop
2. Open Claude Desktop
3. Put system into Hibernate (shutdown /h)
4. Resume from Hibernate
5. Observe Claude Desktop window → white/blank screen

Expected Behavior

Claude Desktop should recover and render normally after Hibernate resume, similar to other Electron apps that handle display context changes properly.

Actual Behavior

• Window appears but content is completely white/blank
• Only fix is to kill Claude processes via Task Manager and restart
• Issue is reproducible every time

Workaround

Kill all Claude processes and restart the application.

Additional Context

This appears to be an Electron rendering issue where the GPU context is lost during Hibernate and not recovered on resume. The external monitor likely exacerbates this because Windows may report different display configurations during the resume process.

Related issues with blank screens: #2230, #3592, #15368

This is a standard laptop workflow (hibernate + external monitor) and should be handled gracefully.

What Should Happen?

Not seeing a white blank desktop app after hibernate
