and help pretty please. I am going nuts over this issue. I am running
(read: GTX 570 Nvidia) and doing the nvidia prop closed source driver. In contrast to the open source driver solution this one set the screen resolution right. I am even running compiz-fusion with nice effects, but I seem to be lacking total 2d acceleration. A transparent terminal that I move around has some vertical flickering, same goes for video playback (vlc). Overlays, like Sxipper for Firefox does not render the page darker but pitch black.

I am not sure if this matters, but
there are uncacheable items in the mtrr. glxgears run smooth at ~14k fps. There is however, no mentioning of mtrr in the bios, not sure if i can (re-)set it there.

I am chewing on this problem for days now. I even switched from an ATI Card (HD5770) to NVIDIA (GTX 570) in hope of a solution.
I have uploaded all relevant files here: http://stuff.demonlord.de/ubuntu/
ANY help is oh-so-glady accepted.
Help. Pretty please.
