<pre>nir_opt_algebraic was converting log2(a) - log2(b) into log2(a/b). We were
still relying on GLSL IR for fdiv lowering, which happens before NIR, so this
fdiv actually made it to the backend. I've written a patch to do fdiv lowering
in NIR.
With all of those fixes, it seems to be running with no fade-to-white. Feel
free to give my 'mordor' branch a try:
