Step 3. Describe the issue

Logs

No immediate error output in console. 
The issue appears to be a rendering/layer conflict rather than a crash.

Reproduce:

1. Press Ctrl + Super + P to switch the panel style to the Windows style
   (I'm not sure of the official name, but it's the one with the bar at the bottom).
2. Trigger a Polkit prompt by: - Opening an application like Timeshift.
   • Or running the command: pkexec echo "Test" in a terminal.
3. The screen immediately turns black.
4. Ctrl + Alt + Del can still work

Reminder

• I agree that it's usually impossible for others to help me without my logs.
