RADEON_DEBUG=fp,vp

In Anno1701, there are flickering colorful spots over some models. It looks similar to the bug 60552, except the spots are colorful instead of black and they don't go away with RADEON_DEBUG=noopt. 

Setting Wine to use ARB shader rendering backend instead of GLSL makes the problem go away indicating another bug in the shader compiler. 

Apitrace here http://pavel.ondracka.cz/Anno1701.trace (renders fine with
proprietary NVIDIA drivers).
