Created attachment 125995 [details] New crash information added by DrKonqi plasmashell (5.18.0) using Qt 5.12.4 - What I was doing when the application crashed: - Unusual behavior I noticed: Every window in the session was covered by some black strange lines. Also, it was randomly closing those windows. -- Backtrace (Reduced): #6 0x00007f26a739a44a in wl_proxy_marshal_constructor () at /lib/x86_64-linux-gnu/libwayland-client.so.0 #7 0x00007f26a3e9d85b in QtWaylandClient::QWaylandWindow::handleUpdate() () at /lib/x86_64-linux-gnu/libQt5WaylandClient.so.5 #8 0x00007f26a1415740 in () at /usr/lib/x86_64-linux-gnu/qt5/plugins/wayland-graphics-integration-client/libqt-plugin-wayland-egl.so #9 0x00007f26a7ee77f1 in QOpenGLContext::swapBuffers(QSurface*) () at /lib/x86_64-linux-gnu/libQt5Gui.so.5 #10 0x00007f26a9599caa in () at /lib/x86_64-linux-gnu/libQt5Quick.so.5
