Could you please install debug symbols for KWin, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports Thanks! I'll install the debug symbols and send a better report. Thanks. Created attachment 151759 [details] dr konqi output with debug symbols I have installed the following packages, then reloaded the dump in Dr. Konqi's window: libqt5qml5-dbgsym libqt5qmlmodels5-dbgsym libqt5qmlworkerscript5-dbgsym libqt5core5a-dbgsym kwin-x11-dbgsym also, I see there's a mention in the new output about snap-assist, I'm using the snap-assist script: https://github.com/emvaized/kde-snap-assist So I'll try to run Kwin with this script disabled/deleted and then, with an upgraded one if I find a new version. Also, I got to trigger the bug precisely trying to screenshot an Edge browser window running Youtube (with snap-assist script enabled). So I'll try to repeat this and see if there's a pattern there. Thank you very much for your time, and I'll keep you posted. Sounds good, thanks! The latest backtrace is better but still missing a few symbols: Thread 1 (Thread 0x7efe2f9299c0 (LWP 79848)): [KCrash Handler] #4 0x00007efe36c50eb4 in KWin::Window::output() const () at /lib/x86_64-linux-gnu/libkwin.so.5 #5 0x00007efe36c7074a in KWin::Workspace::clientArea(KWin::clientAreaOption, KWin::Window const*) const () at /lib/x86_64-linux-gnu/libkwin.so.5 #6 0x00007efe36c09abf in () at /lib/x86_64-linux-gnu/libkwin.so.5 #7 0x00007efe36c0a9a3 in () at /lib/x86_64-linux-gnu/libkwin.so.5 #8 0x00007efe36c0aa25 in () at /lib/x86_64-linux-gnu/libkwin.so.5 #9 0x00007efe367ad5c5 in QQmlObjectOrGadget::metacall(QMetaObject::Call, int, void**) const (this=this@entry=0x7ffe567019e0, type=type@entry=QMetaObject::InvokeMetaMethod, index=<optimized out>, index@entry=101, argv=<optimized out>) at ../../include/QtQml/5.15.5/QtQml/private/../../../../../src/qml/qml/ftw/qflagpointer_p.h:351 I didn't had the time to install the missing stuff to get more debug information, but since I deleted the kwin script snap-asist I'm not having any failures (tried several times to trigger them), till now I see everything working rock solid. I'll keep you posted, but right now it seems the script was causing Kwin to crash. Yep, see Bug 458598. It seems like many people are missing a package and it causes the script to freak out and make KWin crash, *** This bug has been marked as a duplicate of bug 458598 *** I've been testing the newer snap-assist with the latest KDE Neon (some QT packages were updated just yesterday), and now (few moments ago), had a crash, just like the crash with the previous versions (both, snap-assist and KDE Neon). This is happening in a multi-monitor setup (this time it was triggered by changing virtual desktops + moving "half-monitor" windows, thus triggering the snap-assist popup), didn't happened when I was just using snap-assist with one monitor (laptop). Previously, I was testing KDE Neon (latest), WITHOUT snap-assist (deleted from Kwin scripts), and it worked just fine with one monitor, two monitor setups. Now I've just deleted snap-assist and I'm testing latest KDE Neon (logged out, logged in, compositor re-enabled). |
Created attachment 151732 [details] from Dr. Konqi SUMMARY *** Under heavy use of many windows, clicking icons on the plasma panel, or switching tabs - by clicking - in a browser, switchting tabs - by clicking - in konsole, etc. Kwin crashes, restarts and / or disables compositing. After several crashes, in System Preferences, the compositor gets disabled. In multi-monitor setups (two, three), the entire desktop "flashes" in the crash, screens go to full black, then they come back with Kwin crashed, sometimes with the compositor enabled but, after several crashes, the compositor gets disabled. Everything seems to work well with the compositor fully disabled. *** STEPS TO REPRODUCE 1. Open lots of windows 2. Fastly switch of windows by clicking them in the plasma panel 3. You should see Kwin crashing.
