Christopher, thanks for your reply. I uploaded more info by running "sudo apport-collect -p xorg 1617583". Sorry for not giving all information the first time.
I am not sure if it makes sense to really look into the details, because I have no idea how to reproduce the system freeze. No freeze for many minutes does not mean it won't. I couldn't match the freezes to any action/program/etc. For me, the workaround is satisfying. I reported the bug only for give a hint for similar bugs. Please let me know, if I should run additional commands.
