Sentry Crash Report:

Description tockar 2018-12-18 19:16:46 UTC 
Application: kwin_x11 (5.14.4)

Qt Version: 5.11.1
Frameworks Version: 5.52.0
Operating System: Linux 4.19.8-300.fc29.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Firefox was open with youtube tab opened, video paused.
Crash happened when I launched Divinity: Original Sin - native Linux port but requires additional "fixes" to work with open source AMD drivers (I have RX 580).
This never happened before. I have ~65h played and KWin crashed for the first time.

Fedora 29, updated daily.

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".

Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install debug packages and attach a new backtrace.
Comment 2 Vlad Zahorodnii 2018-12-19 11:42:13 UTC 
@Martin Could it be a bug in libepoxy? When we unloading effects, we call effects->makeOpenGLContextCurrent(), so the blur effect should gracefully release all resources.

Oh, shoot, I think I figured out what's wrong. I'll submit the fix a little bit later.

No, false alarm.
Comment 5 Martin Flöser 2018-12-19 16:06:53 UTC 
@Vlad: I don't try to derive anything from incomplete backtraces. It's shooting into the dark without any chance of hitting.

Given

#21 0x00007ff5994322e0 in KWin::Compositor::suspend(KWin::Compositor::SuspendReason)

and

#16 0x00007ff59945112a in KWin::EffectsHandlerImpl::unloadAllEffects() () at /lib64/libkwin.so.5
#17 0x00007ff5994511bb in KWin::EffectsHandlerImpl::~EffectsHandlerImpl() () at /lib64/libkwin.so.5

I think we don't need a backtrace with debug symbols.
