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 happ=
en;
* 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 s=
ince
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 happ=
ens
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.
