The slowdown gone, but I have screen freeze issue now. Like, the screen is not always updated and if you click somewhere you think nothing happened but if you minimize and restore window, you see that click worked.

I'm experiencing both desktop corruption and slow performance of desktop effects. I've tried to downgrade mesa to 8.0.4 and that fixed the problem. Attached is a video comparing the two. The video does not show the desktop corruption I mention (vertical lines appearing) but I will attach a screenshot of that. I originally thought this was related to bug 1042211 but they told me to file another report since it seems to be different artifacts that I'm seeing. Of course I can't say for sure whether the slow performance and the artifacts are due to the same problem but the artifacts seem to appear when the desktop effects are activated. As you can see in the video, mesa 9.0 displays much "jerkier" effects and it seems that when the artifacts come this jerking becomes really bad just before the artifacts appear. Just now I did notice that the artifacts appeared at the mouse pointer when I clicked in a window. The artifacts followed the mouse pointer as I moved it but after clicking a few times they disappeared. WORKAROUND: As described in bug 1042211 I downloaded the 8.0.4 version of mesa from https://launchpad.net/ubuntu/+source/mesa/8.0.4-1ubuntu1. This fixed the problem for me. Since it took a little while for me to figure out how to get the .deb packages from that page, here is how for anyone who wants to try: 1) Go to the above page. 2) Under "Builds" select your architecture 3) This will bring you to a page with all the .deb files for your architecture. I only installed the libgl1-mesa-dri, libgl1-mesa-glx, libglapi-mesa and libglu1-mesa packages. Please let me know if you need more information. p.s. I had some problems choosing the package for this bug. It wouldn't let me put it on libgl1-mesa so I put it on libgl1-mesa-dri.
