With the current git version the distortions are gone and all looks ok.
glxinfo now:

Could you possibly bisect the fix, so that we can get it to 7.10.x?

Do you mean finding the git commit between 7.8 and 7.9 after which the issue
appeared?

I mean finding the "fix", i.e. when it started to work again.

Ok, I reverted back to 7.10.2 and libdrm 2.4.23.
but the bug didn't show up as I expected.
But by also reverting the kernel back to 2.6.32 the bug was there again.
So
Mesa 7.10.2 + Kernel 2.6.32 -> bug
Mesa 7.10.2 + Kernel 2.6.38 -> no bug
It seems that it actually was a kernel issue and not a Mesa one.

OK. I am closing this as NOT-OUR-BUG. r300g in Mesa 7.11 doesn't support old
kernels anyway (the last supported kernel is 2.6.34 and even that one contains
some bugs AFAIK).
