Bug ID: 372304
Summary: kwin_x11 crashes frequently on me when opening a
window/application (Intel Skylake Graphics)
Product: kwin
Version: 5.8.3
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: dev...@t-online.de
Target Milestone: ---
Application: kwin_x11 (5.8.3)
Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.8.6-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
Kwin_x11 randomly crashes when just opening windows/programms, several times
per day.
- Unusual behavior I noticed:
As a result of the crashe(s), the open window(s) are not correctly rendered, I
mean the graphical glitches. Some parts of the window(s) like titelbars
are out of the screen...
- Custom settings of the application:
I am not sure if related, but I use the 'Plastik' window decoration (Don't like
the breeze decoration), 'Breeze' as "Widget style" and the rest
(Color,Look and Feel, Desktop Theme) is "Breeze Dark".
A graphics driver is not installed (modesetting)
https://linux.die.net/man/4/modesetting and no other graphics settings are
set/changed (xorg,kernel parameters).
One more thing(not bug relevant) is that with same hardware, same OS/Apps, but
other DEs (mainly Xfce and Mate without the KDE apps),no crashes...
Now, I am quite sure there are other similar bug reports related to Kwin_x11
crashes, so what makes my report different/relevant..? Well, I have
honestly no idea, all I know is that it's annoying with this frequent crashes
(on two machines, thinkpad L460 and E130) and hopefully it get fixed "soon".
It wasn't actually intended to submit this bug report, because I know that it's
difficult to reproduce but "DrKonqi" said I should, so I did :)
The crash can be reproduced sometimes.
