[Bug 43239] The Witcher 3: ground is too dark in some areas

--- Comment #13 from scix  ---
With more testing, I've found that the patch doesn't work with the nvidia
binary drivers if you force a core context (setting MaxVersionGL to 30002). If
I leave it to use a compatibility context, the bug is fixed. However, using a
core context with this patch works fine with the Mesa driver (it of course
won't work any other way).

I seem to remember there being a staging patch that forces a core profile, but
I don't know if that is just for Mesa, or all cards.
