Bug ID: 491709
Summary: Plasmashell Freeze/Crash upon Animation; "The cached
device pixel ratio value was stale on window update."
Classification: Plasma
Product: plasmashell
Version: master
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org

shell output of multiple "plasmashell --replace"
SUMMARY:
Plasmashell crashes, 100% cpu usage, needs to be killed/restarted manually
Crashes frequently but i can't reproduce it reliably. But the times i noticed
it so far
1) Opening a new app, movement on the taskbar froze
2) Trying to open the clipboard widget, never opened, couldnt unhide my taskbar
anymore
3) Notification popped up, couldnt unhide my taskbar anymore
4) While writing this report,
It feels like my fan spins up shortly before the crash occurs, just now i heard
the fan, could unhide the taskbar, but it froze mid animation.
When i check HTOP plasmashell cpu usage is at 100% for one core. Tried to
pinpoint it by running "plasmashell --replace" and it died at the same spot
every time:
"The cached device pixel ratio value was stale on window update. Please file a
QTBUG which explains how to reproduce."
I get one of these lines whenever some animation runs? I tried real fast:
Opening clipboard widget, preview window in taskbar, Bluetooth widget; but it
does not always crash.
See attachment for more.
I am only noticing this for the last 2 days or so, since the last batch of
updates i did. I dont know which updates it were tho.
