[BUG] Blank/white screen on Windows ARM64 - requires process kill to recover

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

Claude Desktop repeatedly goes to a completely blank/white screen, multiple times per day.
The blank screen never occurs while the app is actively visible and in the foreground. It only happens when the app is not visible:

After switching to another application (Claude window behind other windows)
After minimizing to the taskbar
After any period where the Claude window is occluded or not rendered

When switching back to Claude, the window frame is present but the content area is entirely blank/white. No amount of clicking, resizing, or waiting restores it.
The only recovery is to fully kill the app from the system tray (right-click > Exit does not always work, sometimes requires Task Manager to end all Claude processes), then relaunch.
I have already tried disabling GPU/hardware acceleration in the app settings. The problem persists with GPU rendering turned off, which rules out a simple GPU context loss and suggests the issue is in Electron's rendering or compositing pipeline at a level that the hardware acceleration toggle doesn't address. Running on ARM64 with Snapdragon may compound this due to limited driver support for Electron's rendering pipeline.
Related but distinct from #21803 (hibernate trigger + external monitor), #3592 (minimize trigger), and #15368 (process persistence). This report is ARM64-specific, triggered by any window occlusion, with no external monitor, at very high frequency.

What Should Happen?

Claude Desktop should correctly repaint and re-render its content when the window returns to the foreground, regardless of how long it was occluded or minimized.

Error Messages/Logs

No error messages are displayed. The window simply shows a blank/white content area.

Steps to Reproduce

1. Open Claude Desktop on a Windows ARM64 device (Snapdragon X Elite)
2. Use the app normally (start a conversation, etc.)
3. Switch to another application so the Claude window is fully behind another window, or minimize it to the taskbar
4. Wait any amount of time (sometimes seconds, sometimes minutes)
5. Switch back to Claude Desktop
6. Content area is blank/white. Window frame and title bar are present but no content renders.
7. Only recovery is killing all Claude processes via Task Manager and relaunching.

Additional Information

• Disabling GPU/hardware acceleration in the app did not resolve the issue
• No external monitor or docking station involved - laptop screen only
• Frequency is very high: multiple times per day, essentially every time the app loses foreground focus for more than a brief period
• Touch-enabled device (10 touch points) though I don't believe touch input is related
• The app is kept up to date (auto-updates on launch)
