Just tried your latest version. Unfortunately still no result. Attached the new main.log.
I also tested with Visual Effects = None, but still same result.
As far as I could think of I don't have anything extraordinary on this system. All I could think of is that I'm using the proprietary nvidia driver. From non-ubuntu repositories there is only the skype package and a libdvdcss2. Doesn't seem anything special. Theme is the default Human.
