http://source.winehq.org/git/wine.git/commit/ 997d4ef44f0f9e2284f99d7ce9ec135d68b30c7b
Tried the testcase.
with-wine-staging 2.1 all grey but when I did something to the window it showed black retangle.
with wine 2.2-git it showed the black retangle instantly.
Now both wine and wine-stagnig give the same result.
wine 2.5-git and staging 2.4.
I believe this bug was fixed long ago and was actually a dupe.
