Description Patrick Auernig 2022-12-19 16:52:35 UTC

SUMMARY
***
When showing a notification popup the panel and notification itself freeze until being hovered over and closed.

I don't know is this only happens in Wayland, or if X11 is also affected.
***

STEPS TO REPRODUCE
1. Trigger any desktop notification
2. Panel and notification freeze instantly or after a short delay

OBSERVED RESULT
Noticed at first that the notification timer wasn't going down, or stopped going down after reaching up to half way.
Then I realized that the entire panel froze, because the time was behind by 15 minutes.

EXPECTED RESULT
Notification times out and panel is unaffected

SOFTWARE/OS VERSIONS

KDE Plasma Version: 5.26.4
KDE Frameworks Version: 5.101.0
Qt Version: 5.15.7

When sending a basic notification through QDbus with summary "test" and a timeout of 15000ms it seems to stagger at points, taking much longer than the specified timeout to complete.
In my test case it took about 40 seconds total.

Are you using mesa-git?

I'm currently using Mesa 22.3.1

Might also be worth noting that I'm using 2 screens, and  the popup getting completely stuck might have something to do when one application is in fullscreen mode.
Need to test this further to be sure though.

So many recent mesa regressions affecting Plasma. :(
