Comment 1 Martin Flöser 2017-07-15 18:12:58 UTC

As a workaround use the breeze window decoration.

This looks very much like an OpenGL driver issue. Please verify that your driver is properly installed. You can attach an output of glxinfo.

Comment 2 Michael Lashkevich 2017-07-15 22:58:51 UTC

It turned out that the crashes were caused by the NOUVEAU X server, which started instead of the NVIDIA proprietary server due to a mistake I made during the kernel update. When I succeeded to start the NVIDIA server, the crashed ceased.
