Bug ID: 396830
Summary: kwin_x11 crash when suspending compositing
Product: kwin
Version: 5.12.6
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: anssi.hann...@iki.fi
Target Milestone: ---
Application: kwin_x11 (5.12.6)
Qt Version: 5.10.1
Frameworks Version: 5.47.0
Operating System: Linux 4.17.6-200.fc28.x86_64 x86_64
Distribution: "Fedora release 28 (Twenty Eight)"
-- Information about the crash:
- What I was doing when the application crashed:
I started game "FTL" via Steam and kwin_x11 crashed. From the backtrace it
looks like compositing was being suspended and the crash occurred when effects
were being unloaded.
I retried and the crash did not reoccur.
This is with the Intel drivers (HD Graphics 620 (Kaby Lake GT2)) and I have not
customized kwin compositing settings.
The crash does not seem to be reproducible.
-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
28 return SYSCALL_CANCEL (nanosleep, requested_time, remaining);
