Anyone using Gnome3 and playing any full-screen games? World of Goo is additionally challenging when I can't move my mouse to the top of the screen...
I have several problems when using full-screen programs. The performance drops terribly, and sometimes I can see the gnome-menu and there are areas where the cursor can't go.
I found a solution, install openbox without any addition and use it in those cases
Unfortunately I think I'm heading in that direction. I like where gnome-shell is going but I'm not sure it's there yet.
