--- Comment #15 from Marti <marti at juffo.org> ---
I have the same symptoms when playing Borderlands 2 in Wine with Radeon HD
5850; in certain scenes I see flickering between proper frames and
half-rendered frames, accompanied by the same "*ERROR* Failed to parse
relocation -12!" messages in dmesg.

Running up-to-date Arch Linux 64-bit, kernel 3.12.5, mesa 10.0.1, xorg-server
1.14.5, wine 1.7.9. 

Any extra info I can provide?

I have 8GB of RAM; at the time of this occurring, only 3.4GB is shown as used
in htop (excluding cache); only 17MB of swap is used. My system is nowhere near
out of memory.

So there's definitely something else going on. Is it possible that it's making
unreasonably large allocation attempts? Out of low memory? Memory too
fragmented? Might it have something to do with the fact that the game process
is 32-bit and runs out of address space?

Here's the dmesg message I see repeated lots of times:
