[Bug 45683] Gothic 2 frozen when focused

https://bugs.winehq.org/show_bug.cgi?id=45683

--- Comment #6 from [e-mail] ---
Some additional information:

ddraw_surface_update_frontbuffer is --- with exception of loading screen ---
always called this way:

ddraw_surface_update_frontbuffer(surface  , rect , read, swap_interval)
ddraw_surface_update_frontbuffer(0x9948cf0, (nil), 0   , 1);

Taking away focus and giving it back does not change anything, yet game
actually runs without focus and is fronzen with focus. DDRAW_SWAPPED in
surface->ddraw->flags is alway set.
