It crashes with SIGFPE, so it seems to be some floating point or math error. This happens pretty often, usually about once a day. Apparently fixed with: https://invent.kde.org/plasma/kwin/-/merge_requests/5776 in 6.0 `calculateWindowTransformationsNatural` has also been replaced in 6.1 with a new layout algorithm |
SUMMARY KWin for Plasma 6 often crashes, was fine with Plasma 5. I never pay enough attention to figure out how exactly it happens, but I think it's related to the top-left hot corner trigger action and when hitting it, and it's showing one of the possible window overview layouts. I captured a backtrace for plasma 6.0.5/kwin_wayland 6.0.5 on openSUSE Slowroll: #0 0x00007ff832a125bc in ExpoLayout::calculateWindowTransformationsNatural() (this=this@entry=0x55c131b67af0) at
