Bug description:
I have Kubuntu 12.10 set up on a ThinkPad T430.
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.
