You are mixing two unrelated backtraces. In the first, pa_fdsem_post() causes abort(), might be a pulse-audio issue. In the second, wl_proxy_marshal_array_constructor_versioned() crashes (issue is in KWayland, QtWayland, or in Wayland).
it happened again after upgrade to Qt 5.14 Operating System: Arch Linux KDE Plasma Version: 5.17.4 KDE Frameworks Version: 5.64.0 Qt Version: 5.14.0
It happened again, this time on Plasma 5.18.2. Plasma froze, ~5 minutes later it crashed and tried to restart itself, without success. Then I used krunner to run "plasmashell --replace" a few times, wallpaper and panel appeared but plasma always crashed again after a few seconds. Restarting Plasma session was only way to make my system usable again. Operating System: Arch Linux KDE Plasma Version: 5.18.2 KDE Frameworks Version: 5.67.0 Qt Version: 5.14.1
Could you please clarify which of the two backtraces you are getting with Qt 5.14.0? According to bug 408847 comment 20 the wl_proxy_marshal_array_constructor_versioned() crash shouldn't be happening.
My backtraces were posted before Qt 5.14 to be released.
Comment 2 and comment 3 state that you are getting this bug again after updating to Qt 5.14, but didn't state which of the two reported issues you are referring to. Adding an updated backtrace would clarify.
Created attachment 133944 [details] screenshot This problem happened again, this time on neon unstable. Tooltip of digital clock got stuck and flikering on the screen, Plasma froze completely and became desaturate, as we can see in the attached screenshot.
