Bug ID: 361563
Summary: Weird behavior on multi screen setup and crashes
Product: plasmashell
Version: 5.6.1
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Application: plasmashell (5.6.1)
Qt Version: 5.5.1
Frameworks Version: 5.20.0
Operating System: Linux 4.5.0-3-default x86_64
Distribution: "openSUSE Tumbleweed (20160117) (x86_64)"
-- Information about the crash:
- What I was doing when the application crashed:
moving a window
- Unusual behavior I noticed:
windows are small, have a fixed size, moving them makes them disappear or
crash.
See here for a video and screenshots/pictures of the behavior:
https://cloud.josandcamila.com/index.php/s/Hbl07hLaUWriMrf
This is possibly related to the kwin crash here:
https://bugs.kde.org/show_bug.cgi?id=361551
(I'm trying to reproduce that one but now plasma crashes on me)
I hope this is enough info to find the culprit...
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
