I am running into a problem where my KDE Plasma taskbar (example pictured below) freezes randomly every so often.

KDE Plasma 5.27.8 taskbar

The only way to unfreeze the taskbar (and get it to render in a current state) was from a solution I found here which inspired me to write the following script:

killall plasmashell && kstart5 plasmashell 
(kquitapp5 plasmashell && kstart5 plasmashell) & >/dev/null &

It's nice that I have found a way to manually get out of the frozen state, but I am trying to find a solution that doesn't entail me having to stop what I am doing to run a script because of a bug. All of this is to ask:

  1. Is there a way to trigger this script when the taskbar gets into a frozen state? If not...
  2. Is there already a fix for this somewhere?

I am running Kubuntu 23.10, Plasma 5.27.8

Had the same issue, sounds a lot like https://bugs.kde.org/show_bug.cgi?id=469016

That issue is already fixed but the fix will only come out in plasma 6.0

You can mitigate it by disabling previews (right click icons-only task manager -> configure icons-only task manager -> appearance -> general and disable show small window previews when hovering over tasks)
