In Anno1701, there are flickering colorful spots over some models. It looks
similar to the <a class="bz_bug_link 
          bz_status_NEW "
   title="NEW --- - [r300g] Carvisualizer webgl demo: black flickering spots over the car"
   href="show_bug.cgi?id=60552">bug 60552</a>, 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 <a href="http://pavel.ondracka.cz/Anno1701.trace">http://pavel.ondracka.cz/Anno1701.trace</a> (renders fine with
proprietary NVIDIA drivers).
