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 Linux: 6.1.0 KDE Plasma Version: 5.26.4 KDE Frameworks Version: 5.101.0 Qt Version: 5.15.7 ADDITIONAL INFORMATION GPU: integrated graphics CPU: AMD Ryzen 5 7600X
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?

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. :( *** This bug has been marked as a duplicate of bug 462216 ***
