tmp: disable buggy window emulation 

I'd like to merge my affine sprite impl into main, which will require
merging a lot of the rewrites I did in this branch. My plan is to
merge the buggy ppu window impl to main, but keep it disabled.

This is technically a regression but the current impl barely worked
anyways so....
