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.
@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. *** This bug has been marked as a duplicate of bug 396830 ***

@Vlad: I don't try to derive anything from incomplete backtraces. It's shooting into the dark without any chance of hitting.
