I have got a problem since I have updatet to unity 5.8 (3D)
I still have a Launcher and a Top-Menu, the problem is, the launcher is flashing if im going with my mouse over it and there are some grafical errors and I've got a black bar unter the top-menue which is over my tabs from firefox for example.
Ubuntu says that I have unknown grafical drivers, but hardinfo finds my intel Mobile GM965/GL960 and all worked fine before updating to unity 5.8.
