Re: nVidia driver 1.0-96xx causes glitches, artifacts and crashes on Ubuntu Edgy/Feisty
I'm afraid that this sounds like expected behavior. Maya uses an overlay to render alot of its menus & widgets. Overlays are not expected to work with Composite, currently. If disabling Composite completely eliminates the problems, then I suspect you're not hitting the same problem(s) as others have reported in this thread.
