I assumed it was something with Mesa/DRI/graphics stack. It usually is, but I doubt it now. I am running Intel Sandy Bridge, but the way, but I also have and Optimus NVidia that should be disabled 'games' is not the main repo. I was not sure how things are handled in OpenSUSE; if the bug would even be looked at. In the end I was hoping you have a 'bisect-like' tool, if it was reproducible. > What openSUSE Version are you playing this on?
