SUMMARY after suspend it takes many seconds before login prompt activates when logged in, the activity switch sidebar is frozen ( the cpu widget normally is active, but is now frozen ) nothing responds. open windows of applications still work, but overlapping windows are not being handled by the window manager STEPS TO REPRODUCE 1. suspend system 2. wake it up (keyboard press or power button ) 3. notice unresponsiveness of act. switcher OBSERVED RESULT activitity switcher frozen has to be reset with : open a terminal : I have keyboard custom shortcut, ctrl-win-alt + k , it starts a konsole window. _____________________ $ killall plasmashell $ kstart5 plasmashell _____________________ EXPECTED RESULT activity switcher should function as it used to do SOFTWARE/OS VERSIONS Operating System: openSUSE Leap 15.6 KDE Plasma Version: 5.27.11 KDE Frameworks Version: 5.115.0 Qt Version: 5.15.12 Kernel Version: 6.4.0-150600.23.47-default (64-bit) Graphics Platform: offscreen Processors: 12 x AMD Ryzen 5 5600 6-Core Processor Memory: 31.2 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1650/PCIe/SSE2 ADDITIONAL INFORMATION this started after updating to opensuse 15.6 I also started using brave browser, some weeks before the update. No issues noticed (just saying. its the only major change I remember )
correction : the window manager does handle windows, one can move them around, their appearance does not get destroyed by each other. you can switch with alt - tab but not with the activity bar, since it is frozen.
please check attached part of /var/log/messages it is the logging from finished awake from sleep until I start my xreplasma script to get the taskbar working again. 2025-04-25T03:23:41.827815+02:00 dep8 systemd[1]: Finished System Suspend. 2025-04-25T03:23:41.827976+02:00 dep8 systemd[1]: systemd-suspend.service: Consumed 1.018s CPU time. 2025-04-25T03:23:41.828326+02:00 dep8 systemd[1]: Stopped target Sleep. 2025-04-25T03:23:41.828428+02:00 dep8 systemd[1]: Reached target Suspend. 2025-04-25T03:23:41.829828+02:00 dep8 systemd-logind[1272]: Operation 'sleep' finished. 2025-04-25T03:23:41.830279+02:00 dep8 ModemManager[1273]: <info> [sleep-monitor-systemd] system is resuming 2025-04-25T03:23:41.872197+02:00 dep8 systemd[1]: Starting NVIDIA system resume actions... 2025-04-25T03:23:41.872552+02:00 dep8 systemd[1]: Stopped target Suspend. 2025-04-25T03:23:41.873840+02:00 dep8 suspend: nvidia-resume.service 2025-04-25T03:23:41.873875+02:00 dep8 logger[28520]: <13>Apr 25 03:23:41 suspend: nvidia-resume.service 2025-04-25T03:23:41.877445+02:00 dep8 systemd[1]: nvidia-resume.service: Deactivated successfully. 2025-04-25T03:23:41.896029+02:00 dep8 systemd[1]: Finished NVIDIA system resume actions. greet : 2025-04-25T03:23:42.743175+02:00 dep8 kscreenlocker_greet[27871]: qt.virtualkeyboard.hunspell: Hunspell dictionary is missing for "en_GB" .

furthermore: top says kplasma eats a whole cpu. 100% dolphin hangs, other tasks do not ( i can move them around normally ) restarting without dolphin results in kplasma returning to normal, after 2 or 3 minutes.
although... dolphin is not the cause. cannot reproduce that, even without any open apps the thing is still frozen / non responsive.
My config is separated: / for operating system, data etc is mounted on a separate filesystem. I installed a fresh opensuse 15.6 and linked my thunderbird, mozilla etc directories in my /home/user on / to my data filesystem. the problem disappeared. apparently something in the root config caused the problem, since my user data did not change a single bit.... I think this bug needs to be closed. I still have the 15.5 install; if anyone is interested, let me know.
