Dual P4 Xeon, 2 GB RAM, Mesa HEAD is: commit 110009302bddb4c42a5b3ed5ca451d6bb50a06a0 Author: Fabio Pedretti <fabio.ped@libero.it> Date: Wed Nov 6 10:55:28 2013 +0100 gallium: fix build on GNU/kFreeBSD I am currently playing WoW with my HD4670 (AGP), and I am noticing that various textures are being rendered incorrectly when viewed beyond a certain distance. However, as I approach the badly rendered area, all of the artifacts disappear! It's as if my character is surrounded by an invisible bubble, and everything within the bubble becomes correctly rendered. (The visual effect reminds me of the "Genesis wave" demonstration video from "Star Trek: The Wrath of Khan" - if that means anything to anyone...;-).) This problem is not visible with the HD4890 on my 64 bit machine. I have attached a couple of screenshots showing the problem.

Maybe an AGP problem? Does booting with radeon.agpmode=-1 on the kernel command line in grub help?
(In reply to comment #3) > Maybe an AGP problem? Does booting with radeon.agpmode=-1 on the kernel > command line in grub help? Nope, it doesn't make any difference.

Created attachment 95474 [details] Fragment of apitrace from 32 bit WoW on HD6450 (40/40) This trace can be reconstructed via the following command: $ cat wine.trace.xz.* > wine.trace.xz Its SHA1SUM should be: efd80aefa86a65d4e8d1c43cfdd231361414b4bd This texture corruption is now visible on a HD6450 as well as my HD4670 AGP. The corruption is also visible when I replay this trace on my HD4890, although my HD4890 itself renders WoW correctly. Interestingly, my HD4890 replays this trace far more quickly than the HD6450 does. And the HD6450 occasionally renders what appears to be a completely blank frame.
Actually, I've just rewatched this replay on my HD4890 and there are distinct "flickers" of what appear to be blank frames with the card too. The corruption is visible as blue/green patches on what is supposed to be distant red sand.
