Bug ID: 359324
Summary: plasmashell often hangs randomly, sometimes with
broken window preview
Product: plasmashell
Version: 5.5.3
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: thereisntausefuladdressl...@yahoo.com
CC: bhus...@gmail.com, plasma-b...@kde.org
plasmashell hangs at least every hour for an unknown reason. Kwin is still
running and working as expected, I can move windows, switch through them with
Alt+Tab and run commands from krunner (Alt+F2). I can't click anything on the
panel, it simply doesn't react. Sometimes as plasmashell hangs it shows a
broken preview in the taskbar, but I don't have a screenshot of this.
To workaround this I can kill plasmashell and restart it and it continues to
work for a time.
If I run plasmashell in a konsole window, the output doesn't show anything
directly related with the hang. But I get errors like:
QXcbConnection: XCB error: 2 (BadValue), sequence: 8291, resource id:
140509189, major code: 142 (Unknown), minor code: 3
QXcbConnection: XCB error: 2 (BadValue), sequence: 8370, resource id:
125829124, major code: 142 (Unknown), minor code: 3
QXcbConnection: XCB error: 2 (BadValue), sequence: 8439, resource id: 18874372,
major code: 142 (Unknown), minor code: 3
If I move the mouse pointer over a tab in the taskbar.
I made a core dump with gcore, but I'm not sure if I should upload it.
(compressed 13,2MB, uncompressed 3,2GB).
