Yes, apparently something doesn't get re-initialized properly across suspend/resume. It's hard to say at this point whether this is due to the X driver, X server, DRM kernel module or even 3D driver, but it's very unlikely due to compiz. > I'd like to get Michel's opinion on all > this, but I guess we'll end up forwarding this bug upstream soon.
