This is a very weird issue. I think it may not be in Mesa, and here's why:

* On Debian Jessie with kernel 3.16 and Mesa 10.3, the problem doesn't happen;
* On the same Debian, but with mesa backported, the problem also doesn't happen;
* On the same Debian with Mesa backported and the Kernel backported, the problem still doesn't happen;
* On Arch Linux with Mesa downgraded to 10.3, the problem happens;
* On the same Arch Linux with Mesa and Kernel downgraded (Kernel to version 3.16 and even 3.10), the problem still happens;
* I'm not 100% sure I downgraded the Firmware on Arch, but I'll try today since I'm testing a few drivers in Linux;
* On vanilla Arch with Catalyst/FGLRX, the problem doesn't happen;

So I do think this issue is much bigger than everybody thinks and only happens with a certain combination of Mesa, Kernel, Firmware, and possibly libdrm, llvm, and other pieces of software as well.

What I really think is that VALVe should investigate this since this problem started happening after they introduced mandatory Texture Streaming.
