Solved to my liking. System Specs:

Unity and Gnome3 windows now draw consistently without slant. 3D game OpenArena and Sketchup under Wine both work as well. If I do need to activate the propietary ATI/AMD dirvers for any reason, I will post back here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/666715 Title: [ATI Radeon HD 3200] Unity screen drawing problem -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
