Image Artifacts with Intel Integrated Graphics [SOLVED]

egan · 2011-06-06 16:19:13

With xf86-video-intel and 2nd Gen. Intel HD integrated graphics, some larger images, and all images that are larger than the screen in Firefox are messed up.

Example here: http://i.imgur.com/9ylal.png

The top portion of the image is replaced with a duplicate of a more central portion, or often, a duplicate of the bottom portion. Reloading the page skipping cache re-renders the image and it cyclically modulates through different permutations of the same transformation, every once and a while producing the correct image. When large images are loading, they look correct until they are completely downloaded, at which point they instantly bork. Occasionally I get worse artifacts, like horizontal streaks.

I haven't noticed the problem in any other program besides Firefox, but I don't have anything else graphical.

Does anyone know why this might be occurring, and if there is any way to avoid it?

Try kernel 2.6.39 from [testing] oder downgrade to 2.6.37. That fixed it on my machine.

I am not sure what wm you are using, but I had a lot of tearing using XFCE and enabling compositing fixed the issue.

I'm using xmonad. I'll see what happens on the next kernel update.

I am suffering from excessive tearing and bad performance as well, as reported in https://bbs.archlinux.org/viewtopic.php?pid=937487.

Using Gnome, I asked on Gnome Shell's mailing list (see http://www.mail-archive.com/gnome-shell … 4309.html). I was told that the drivers for Sandy Bridge video cards are in a work in progress status and tearing and artefacts are known to developers and will be fixed (I hope soon )

It appears to be fixed with the latest kernel, yay.
