Here is what I am talking about

When I go to play guild wars 2 on open drivers everything works fine until I load up the world. The entire map looks like a "zebra" (especially in the snowy areas). Now when I switch to proprietary drivers like nividia's drivers then the lines go away. This happens on nividia gtx 460, radeon 5750' intel HD 3000 graphic cards.

You mentioned on the xorg mailing list that this worked properly two months ago, so there seems to have been a regression. Can you try bisecting, or at least determining which versions of Mesa are broken / working?

It's pretty hard to say anything useful without logs, but one thing that regularly seems to cause this kind of thing for people is missing S3TC support.

I just read your other email this morning Michel. I would love to provide but I do not know how to do that for mesa or bisecting.

Holy cow enabling S3TC made it all work!
