SUMMARY taskbar freezes. Clock stops updating. This is 5th occurrence in the past few weeks. #1 - rebooted to clear #2 - rebooted to clear #3 - was on zoom call, continued to work on only available desktop. Cleared up on its own. #4 - happened just before I was about NVMe SSD card; so shutdown & rebooted #5 - waited, hoping it would clear up as in #3. Using htop, sent SIGINT to 2nd instance of startplasma-x11 which killed the whole desktop. Hey, was trying to save work on other desktops; lost some Libreoffice writer edits. Which code module creates and manages the taskbar? Guessing startplasma-x11 may be related. I see no processes in unusual states. STEPS TO REPRODUCE 1. no idea; appears to be related to disk activity. Freeze #4 appeared to be related to high disk activity, so reported at https://bugs.mageia.org/show_bug.cgi?id=31080 However, #4 was the only high dish activity situation. This occurrence (#5), I was just editing a document. 2. 3. OBSERVED RESULT frozen taskbar. Stuck on current desktop. After 5th occurrence, appears to be a race condition or waiting for something. Usually, the freeze occurs as the mouse is moved over the task bar and miniature application window representations appear and freeze too as in screenshot at https://bugs.mageia.org/attachment.cgi?id=13486 EXPECTED RESULT no freeze SOFTWARE/OS VERSIONS Operating System: Mageia 9 KDE Plasma Version: 5.25.90 KDE Frameworks Version: 5.98.0 Qt Version: 5.15.6 Kernel Version: 6.0.1-server-1.mga9 (64-bit) Graphics Platform: X11 Processors: 20 × 12th Gen Intel® Core™ i7-12700K Memory: 125.5 GiB of RAM Graphics Processor: AMD Radeon RX 6600 XT Manufacturer: Dell Inc.

Created attachment 153731 [details] journal at the time of taskbar freeze Task bar froze again. This time, I was simply taking screen shots with screengrab for a short document. More clues... I use KDEconnect to my phone. When the bar froze, a patch appeared over the other windows. It was about the same size and location as notifications I often see from the phone; but the content had not yet painted. Looked like the contents of underlying window(s), and never changed. Continued to get screen shots, ignoring the task bar and patch. Oh... every Save of screenshots took 50 seconds each before the file selector disappeared -- may be related or not? After saving my document, I used xkill on the patch -- it immediately disappeared, along with the task bar and desktop which is now solid black and unresponsive to mouse clicks.
