--- Comment #46 from Brendan Shanks bshanks@codeweavers.com --- I also tested MDK2 on 10.11, windowed and full-screen mode seem to work fine.
I'm going to submit this patch upstream, it seems like a clear improvement over the current (broken) upstream state and we can address other issues separately.
