Created attachment 170031 [details] New crash information added by DrKonqi kwin_x11 (5.27.5) using Qt 5.15.8 Crashed occured when drag'n'dropping a file from a local drive to a SMB share. The copy worked, but kwin restarted and windows were reloaded, but slightly off from where the were located. Side note ; everytime I submit a bug report, "The KDE Crash Handler" does submit the bug, but stays stuck forever at submitting it, I have to force it to close and my login information isn't saved and I have to re-enter my credentials every single time. -- Backtrace (Reduced): #7 0x00007fb294175b67 in KWin::EffectsHandlerImpl::prePaintWindow(KWin::EffectWindow*, KWin::WindowPrePaintData&, std::chrono::duration<long, std::ratio<1l, 1000l> >) () from /lib/x86_64-linux-gnu/libkwin.so.5 #8 0x00007fb2942121d3 in KWin::WorkspaceScene::preparePaintSimpleScreen() () from /lib/x86_64-linux-gnu/libkwin.so.5 #9 0x00007fb294212685 in KWin::WorkspaceScene::prePaint(KWin::SceneDelegate*) () from /lib/x86_64-linux-gnu/libkwin.so.5 #10 0x00007fb2941311ef in KWin::Compositor::prePaintPass(KWin::RenderLayer*) () from /lib/x86_64-linux-gnu/libkwin.so.5 #11 0x00007fb29413437f in KWin::Compositor::composite(KWin::RenderLoop*) () from /lib/x86_64-linux-gnu/libkwin.so.5

For me, the crash happened when simply double-clicking a word when editing in my IDE (clion). Regarding graphical effects: It could be that at this moment the IDE was in the process to show a tooltip at the mouse position (the particular IDE is really eager doing this on any opportunity (i.e. mouse pointer standing still for a few milliseconds)).
