SUMMARY Kwin regularly crashes "out of the blue". STEPS TO REPRODUCE While doing no specific action, Kwin crashes. OBSERVED RESULT Kwin crash and automated restart. EXPECTED RESULT Kwin doesn't crash.

Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong: > #7 0x00007f7dc9dcca89 in () at /usr/lib/dri/iris_dri.so > #8 0x00007f7dcaa4ecc5 in () at /usr/lib/dri/iris_dri.so > #9 0x00007f7dc9fd3849 in () at /usr/lib/dri/iris_dri.so > #10 0x00007f7dd410cd48 in () at /usr/lib/libkwin.so.5 Could you please install debug symbols for kwin and mesa, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports The issue is very likely a duplicate of one of the ones reported here: https://bugs.kde.org/buglist.cgi?quicksearch=KWin%3A%3AScene%3A%3ApaintScreen&list_id=2013268 But without the above information, I can't be sure. Thanks again!
I was able to install the debug symbols for Kwin, but not for mesa. They seem to be missing in Arch Linux debug packages. Here is a stacktrace with Kwin debug symbols: > Application: KWin (kwin_x11), signal: Aborted > [KCrash Handler] > #4 0x00007f34fe1f534c in __pthread_kill_implementation () at /usr/lib/libc.so.6 > #5 0x00007f34fe1a84b8 in raise () at /usr/lib/libc.so.6 > #6 0x00007f34fe192534 in abort () at /usr/lib/libc.so.6 > #7 0x00007f34f260e59b in () at /usr/lib/dri/iris_dri.so > #8 0x00007f34f324623f in () at /usr/lib/dri/iris_dri.so > #9 0x00007f34f288fea7 in () at /usr/lib/dri/iris_dri.so > #10 0x00007f3500c17d88 in KWin::WindowThumbnailItem::updateOffscreenTexture() (this=0x561e4d044ed0) at /usr/src/debug/kwin-5.24.4/src/scripting/thumbnailitem.cpp:432 > #11 0x00007f34ff2a9463 in () at /usr/lib/libQt5Core.so.5 > #12 0x00007f3500bef3e6 in KWin::Scene::paintScreen(QRegion const&, QRegion const&, QRegion*, QRegion*, KWin::RenderLoop*, QMatrix4x4 const&) (this=0x561e4c2f90a0, damage=<optimized out>, repaint=..., updateRegion=0x7ffc97548ac0, validRegion=0x7ffc97548ab8, renderLoop=<optimized out>, projection=...) at /usr/src/debug/kwin-5.24.4/src/scene.cpp:282 > #13 0x00007f3500cb5297 in KWin::SceneOpenGL::paint(KWin::AbstractOutput*, QRegion const&, QList<KWin::Toplevel*> const&, KWin::RenderLoop*) (this=0x561e4c2f90a0, output=0x0, damage=..., toplevels=<optimized out>, renderLoop=0x561e4c033820) at /usr/src/debug/kwin-5.24.4/src/scenes/opengl/scene_opengl.cpp:259 > #14 0x00007f3500b517f4 in KWin::Compositor::composite(KWin::RenderLoop*) (this=0x561e4c01ba40, renderLoop=0x561e4c033820) at /usr/src/debug/kwin-5.24.4/src/composite.cpp:633 > #15 0x00007f3500b51d40 in KWin::X11Compositor::composite(KWin::RenderLoop*) (this=0x561e4c01ba40, renderLoop=<optimized out>) at /usr/src/debug/kwin-5.24.4/src/composite.cpp:844 > #16 0x00007f34ff2a9463 in () at /usr/lib/libQt5Core.so.5 > #17 0x00007f3500b0f7a7 in KWin::RenderLoop::frameRequested(KWin::RenderLoop*) (this=<optimized out>, _t1=<optimized out>) at /usr/src/debug/build/src/kwin_autogen/EWIEGA46WW/moc_renderloop.cpp:206 > #18 0x00007f3500be0c18 in KWin::RenderLoopPrivate::dispatch() (this=0x561e4c01fe20) at /usr/src/debug/kwin-5.24.4/src/renderloop.cpp:150 > #19 0x00007f34ff2a9463 in () at /usr/lib/libQt5Core.so.5 > #20 0x00007f34ff2ab69f in QTimer::timeout(QTimer::QPrivateSignal) () at /usr/lib/libQt5Core.so.5 > #21 0x00007f34ff29c766 in QObject::event(QEvent*) () at /usr/lib/libQt5Core.so.5 > #22 0x00007f34fe8a61c6 in QApplicationPrivate::notify_helper(QObject*, QEvent*) () at /usr/lib/libQt5Widgets.so.5 > #23 0x00007f34ff2785aa in QCoreApplication::notifyInternal2(QObject*, QEvent*) () at /usr/lib/libQt5Core.so.5 > #24 0x00007f34ff2c3dd5 in QTimerInfoList::activateTimers() () at /usr/lib/libQt5Core.so.5 > #25 0x00007f34ff2c4272 in QEventDispatcherUNIX::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () at /usr/lib/libQt5Core.so.5 > #26 0x00007f34f917bf83 in () at /usr/lib/libQt5XcbQpa.so.5 > #27 0x00007f34ff27088b in QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) () at /usr/lib/libQt5Core.so.5 > #28 0x00007f34ff27bfd7 in QCoreApplication::exec() () at /usr/lib/libQt5Core.so.5 > #29 0x0000561e4bb71e8c in main(int, char**) (argc=<optimized out>, argv=0x7ffc975494e8) at /usr/src/debug/kwin-5.24.4/src/main_x11.cpp:482 > [Inferior 1 (process 838) detached]
Thanks, that turns out to be good enough. *** This bug has been marked as a duplicate of bug 451612 ***
