--- Comment #5 from imagina...@mailbox.org --- OK, now I caught one, while using openGL-3.1 as compositor. I have attached a stacktrace which I hope is usable. The freeze happened while the PC was unattended for a while, i. e. no input via keyboard or the mouse. The desktop was dead except for the mouse-pointer which could be moved around freely. Klicks had no effect. CPU-load was around zero. I now believe that the other freezes also happened with openGL-3.1 as compositor. I tried openGL-3.1 because I had rendering artifacts with openGL-2.0 in LibreOffice-6.0 (hw-accel. and openGL off) in some documents. XRender was always OK.
