Bug 461688

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
