Hi,

I tested this a little bit sooner than expected, thanks to a
regression in Starcraft and Age of Empires 2. (Looks like bugs 35950
and 35655).

The good news is that your patches fix the regressions in those games.

Kde 4.11.5 here. The fullscreen apps indeed appear fullscreen. But
once Starcraft was shifted down and only showing the top ~50 pixels at
the bottom of the screen.

Inside a virtual desktop Age of Empires 2 seemed to snap into place
after a resolution change. It first rendered at the bottom of the
screen and after ~0.5 seconds the rendering was correct.

Alt-Tab does not work. The game loses focus and stops redrawing, but
my other apps don't show up. Switching to a different virtual desktop
works. I don't know if this worked in the past with those two games,
probably not. I'll retest with plain Wine, as far as the regressions
allow.

I have to select the Wine window. If I select the game window, Wine's
rendering window does not take over.

No issues noticed there, but both games draw their own mouse cursor.

I've also tested Warhammer 40k: Dawn of War, it has the same focus
loss / regain behavior as the ddraw games.
