Created attachment 136913 [details] image showing observed result STEPS TO REPRODUCE 1. on System Settings > Workspace Behavior > General Behavior change animation speed OBSERVED RESULT Session just dies, it kinda renders the same thing over and over. EXPECTED RESULT Session shouldn't die. SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUSE Tumbleweed (available in About System) KDE Plasma Version: 5.21.3 KDE Frameworks Version: 5.80 Qt Version: 5.12.2
Also when rendering the same thing over and over sometimes it renders by itself and sometimes after user input like moving the cursor or typing something
Testing even further, this bug also occurs when enabling "Navigation wraps around" on System Settings > Workspace Behavior > Virtual Desktops. It seems like changing some "important" setting might trigger this bug.
Are you using the proprietary NVIDIA driver?
Settings the NEEDSINFO status.
Yes!
