Bug#848388: /usr/bin/plasmashell: plasmashell - panel freezes, sometimes unstuck by switching to vt1 then vt7
Package: plasma-workspace
Version: 4:5.8.4-1
Severity: normal
File: /usr/bin/plasmashell
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Some unknown upgrade, but this problem has persisted through several upgrades.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Panel time often freezes, and also sometimes windows of applications
(eg firefox, chromium, mpv, konsole). Sometimes they can be unstuck by
switching virtual terminals e.g. to vt1 then back to vt7.
gdb trace when panel clock froze:
