Can you still reproduce this with current Mesa git?

Anyway, this is a game bug. The game generates NaNs, which produces the
artifacts. The game might have been designed for DX9 or GL2 hardware, not GL3.

It shouldn't occur anymore, because NaNs are disabled by radeonsi.

Can you run the program with the environment variables:

MESA_GLSL=dump PIGLIT_PLATFORM=gbm R600_DEBUG=ps,vs,gs


And post the output.

Sqrt(x) results are undefined if x < 0, so the only thing we are allowed to do
is sqrt(abs(x)). That is how RSQ works.
