Hello everyone, I was playing around with this bug earlier today and I believe I've made some progress as locating it. By chance I disabled power management for my monitor, Ubuntu 12.04 has no screen saver so I didn't worry about that, in order to watch a movie without interruption. As luck would have it whenever I enable power management for my monitor I have the video problem; yet when I disable it the problem vanishes. I am currently using the Xorg-edgers ppa to have a heavily updated version of the open source ATI/AMD driver and I experience no issues anymore. Also, this ppa installed 3.5 kernel which appears to be behaving quite well. Even flash plays at full screen now which is amazing. So as a possible band-aid until the problem is fixed I would suggest disabling power management for your monitor - much easier than recompiling a kernel or wading through a git tree. Hope this helps! There wasn't any error messages generated for those interested - I experience the problem just like everyone else...
