Nouveau - May 2014 - OpenArena artifacts since version bump to 1.1.1

Hello!
I'm using NVIDIA GeForce GT 640M. And beginning with this commit:

    commit 142c21b8d493318551932eee2e9d98ff14b473da

    drm/nouveau/drm: bump the driver version to 1.1.1 to report new features

till the latest kernel 3.15-rc5 OpenArena game looks like this:

Is it a known bug? What can I do to fix it?

Using Mesa version 10.0.3.

Ah, it's probably the compression that's breaking things... Do you
also see errors in dmesg about LTCG?

You can try turning it off by setting compressed = false in
nvc0_miptree.c:nvc0_miptree_create.

No. (Debug level is 4.)

It helps.
So indeed, compression causes the problem.
