Created attachment 161890 [details] pacman -Q - list of installed packages SUMMARY kwin_wayland crashed for no obvious reason. Yep, no debug symbols. Maybe I will install it and wait another 1-2 months (it happened before a few times) for to this happen again. STEPS TO REPRODUCE Had 9 hours of uptime doing my stuff. Opened twitch.tv in Firefox, the site was about to load and this happened. OBSERVED RESULT All my programs closed, including those from autostart.

You can use debuginfod to download the debug symbols for an existing backtrace. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl. Can you please follow the instructions there and paste a symbolicated backtrace? Thanks!

Thanks! It took me a while as I ruined a bit my package manager while adding debug repositories :D I'm kind of a noob, so be patient with me, please. Seems like libQt5Core.so.5 debug symbols are of different versions. I hope this will be enough. ``` #0 0x0000563f751261ff in KWin::Xwl::Dnd::handleClientMessage (this=0x7effc0001830, event=0x563f78535b10) at /usr/src/debug/kwin/kwin-5.27.8/src/xwayland/dnd.cpp:123 123 if (drag->handleClientMessage(event)) { [Current thread is 1 (Thread 0x7effead83640 (LWP 1487))] (gdb) bt #0 0x0000563f751261ff in KWin::Xwl::Dnd::handleClientMessage(xcb_client_message_event_t*) (this=0x7effc0001830, event=0x563f78535b10) at /usr/src/debug/kwin/kwin-5.27.8/src/xwayland/dnd.cpp:123 #1 0x0000563f75129a1c in non-virtual thunk to KWin::Xwl::DataBridge::nativeEventFilter(QByteArray const&, void*, long*) () at /usr/src/debug/kwin/kwin-5.27.8/src/xwayland/databridge.h:55 #2 0x00007efff0897fbf in QAbstractEventDispatcher::filterNativeEvent(QByteArray const&, void*, long*) (this=<optimized out>, eventType=..., message=message@entry=0x563f78535b10, result=result@entry=0x7ffef0d8d3c8) at kernel/qabstracteventdispatcher.cpp:495 #3 0x0000563f7513d331 in KWin::Xwl::Xwayland::dispatchEvents(KWin::Xwl::Xwayland::DispatchEventsMode) (this=<optimized out>, mode=<optimized out>) at /usr/include/qt/QtCore/qbytearray.h:463 #4 0x00007efff08d0b37 in QtPrivate::QSlotObjectBase::call(QObject*, void**) (a=0x7ffef0d8d510, r=<optimized out>, this=0x563f7805f640, this=<optimized out>, r=<optimized out>, a=<optimized out>) at ../../include/QtCore/../../src/corelib/kernel/qobjectdefs_impl.h:398 #5 doActivate<false>(QObject*, int, void**) (sender=0x563f7805fda0, signal_index=3, argv=0x7ffef0d8d510) at kernel/qobject.cpp:3925 #6 0x00007efff08d2334 in QSocketNotifier::activated(QSocketDescriptor, QSocketNotifier::Type, QSocketNotifier::QPrivateSignal) (this=this@entry=0x563f7805fda0, _t1=..., _t2=<optimized out>, _t3=...) at .moc/moc_qsocketnotifier.cpp:178 #7 0x00007efff08d2478 in QSocketNotifier::event(QEvent*) (this=0x563f7805fda0, e=<optimized out>) at kernel/qsocketnotifier.cpp:302 #8 0x00007effeff7893f in QApplicationPrivate::notify_helper(QObject*, QEvent*) () at /usr/lib/libQt5Widgets.so.5 #9 0x00007efff089bbf8 in QCoreApplication::notifyInternal2(QObject*, QEvent*) (receiver=0x563f7805fda0, event=0x7ffef0d8d630) at kernel/qcoreapplication.cpp:1064 #10 0x00007efff08e95dc in QEventDispatcherUNIXPrivate::activateSocketNotifiers() (this=this@entry=0x563f76e9b470) at kernel/qeventdispatcher_unix.cpp:304 #11 0x00007efff08ea7a9 in QEventDispatcherUNIX::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) (this=<optimized out>, flags=...) at kernel/qeventdispatcher_unix.cpp:511 #12 0x0000563f752089b2 in QUnixEventDispatcherQPA::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () #13 0x00007efff089a904 in QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) (this=this@entry=0x7ffef0d8d7c0, flags=..., flags@entry=...) at ../../include/QtCore/../../src/corelib/global/qflags.h:69 #14 0x00007efff089bda3 in QCoreApplication::exec() () at ../../include/QtCore/../../src/corelib/global/qflags.h:121 #15 0x0000563f751242fb in main(int, char**) (argc=<optimized out>, argv=<optimized out>) at /usr/src/debug/kwin/kwin-5.27.8/src/main_wayland.cpp:628 ```
