Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install debug packages and attach a new backtrace. Created attachment 122235 [details]
New crash information added by DrKonqi
kwin_x11 (5.16.4) using Qt 5.13.0
Attached you can find a stacktrace with debuginfo packages installed

Backtrace is provided Please post output of
qdbus org.kde.KWin /KWin supportInformation
It seems like left mouse button was being held when you were approaching the bottom right screen corner. Is that true?

kwin support information
(In reply to Vlad Zahorodnii from comment #4) > Please post output of > qdbus org.kde.KWin /KWin supportInformation > > It seems like left mouse button was being held when you were approaching the > bottom right screen corner. Is that true? today the bug happened again. I wanted to use the bottom right corner to switch to the bottom right virtual desktop, so it is possible that I clicked a bit too early. But I cannot reproduce the crash this way, If I actively click before going to the corner then the effect is not starting at all. would you please try again with kwin 5.19+ debug symbols installed desktop effects and compositing settings on and off. (In reply to Mathieu Jobin from comment #7) > would you please try again with kwin 5.19+ > debug symbols installed > > desktop effects and compositing settings on and off. Sadly I cannot reproduce the bug actively, it just happens from time to time, currently using: * Qt 5.15.2 * KDE Frameworks 5.77.0 * Plasma 5.20.4 I will attach a new stacktrace as soon as the crash is happening again. I think I will never see this crash with compositing off as the desktop grid will not work without compositing enabled. Created attachment 134646 [details]
