Thanks. I gave that a shot but still get white instead of the expected black. I see now that we're not actually doing glClear() for this, we're just rendering a black skybox with glFragColor = rgba 0/0/0/1 in the frag shader. The oddity here is that if I draw with a slightly non-black color -- say rgba 0.1/0.1/0.1/1 -- It works as expected and I get a very dark gray. Again, works fine on llvmpipe but not on swr. I'll continue looking at it. Let me know if you have any hunches.
