Yesterday i did the upgrade to 13.04. Its working very well ... except ... i got a transparent grey sqare around my mousepointer. I guess there is some relationship beetween the update of the nvidia driver to ver. 304 and this issue. Maybe its Compiz .. or the X Server. Any ideas how i can fix this? ...
