--- Comment #1 from Matt Fagnani <matthew.fagn...@utoronto.ca> --- I've seen two more kwin_wayland segmentation faults when using Plasma 5.19.2, KF 5.71.0, Qt 5.14.2 while playing videos in vlc. The first such crash had the same trace as I reported here before. The second segmentation fault was in std::__atomic_base<QtSharedPointer::ExternalRefCountData*>::load. Both traces involved QPointer<KWaylandServer::SurfaceInterface>::QPointer at /usr/include/qt5/QtCore/qpointer.h:62 operator() at /usr/src/debug/kwayland-server-5.19.2-1.fc33.x86_64/src/server/pointer_interface.cpp:241 When the mouse pointer is over the video in vlc without moving for a few seconds, the mouse pointer normally disappears. When the mouse is moved after the pointer disappeared, the mouse pointer reappeared. The problem might be related to this mouse pointer disappearing/appearing. Memory corruption might have led to invalid pointers involving the KWaylandServer::SurfaceInterface being passed to QPointer<KWaylandServer::SurfaceInterface>::QPointer. Core was generated by `/usr/bin/kwin_wayland --xwayland --libinput --exit-with-session=/usr/libexec/st'.
