I just finished upgrading my PC to update pack 5. Unfortunately now everything, especially tabs etc. look edgy and wrong... my terminal was also black (I could fix that with preferences).
Here is a screenshot of Nautilus:
The update went without errors. The only thing that happened is that a window popped up while I was typing and somehow hitting space closed it.. no idea what that was and what it was asking for... bad time coincedence :-/
My nvidia driver seems to be installed and working properly, at least the Nvidia X Server settings don't complain or anything... I also ran nvidia-xconfig once again.
Any help would be greatly appreciated!
edit: Oh yes I have restarted my PC
