terminal output

SUMMARY Clicking on the volume/audio icon in the system tray causes a black screen. The mouse cursor remains visible and movable, but the entire desktop shell (plasmashell) becomes unresponsive. The issue is intermittent and typically occurs after several interactions (e.g., on the 10th click). I have to manually run killall -9 plasmashell from a terminal to recover.

STEPS TO REPRODUCE

    Log into a Plasma (Wayland) session.

    Use NVIDIA Driver 580.95.05.

    Click on the Audio volume icon in the system tray multiple times.

OBSERVED RESULT The screen turns black, and the Plasma shell freezes. Only the cursor is visible.

EXPECTED RESULT The audio volume applet should open normally every time without freezing the desktop.
