glmark2 jellyfish vertex shader patch
I confirm that this is happening in SNB (gen6) too.
I modified the jellyfish vertex shader (attached patch) to have the sin()
function argument to be within the range of [0, 2*PI) radians by using the
modulo operation. In this case, it renders fine.
I think this is the same problem explained here:
