Marek Olšák sent in another patch to Mesa that is now in Mesa-git which should hopefully be a better fix for black transitions in The Witcher 2 on radeonsi (AMD).

From the commit message:
Quoteradeonsi: preload PS inputs only if KILL is used
so that most shaders can get lower VGPR usage thanks to lazy input loading.
I think this is a more accurate constraint that prevents the black transitions
in Witcher 2.

Affected shaders (7758):
Max Waves: 57437 -> 58231 (1.38 %)

Really great to see Marek continue to work on fixes for this game and hopefully this will help other games too.

This will likely be in the next release after Mesa 17, which is due next month. Article taken from
