I'm not sure. The GDI object limit is intentional I think. Trying to fill the
vidmem with surfaces is the game's doing, that won't be fixed.

I guess the way to fix this is to rewrite the GDI renderer not to use a DIB
section for every surface, only if it is a primary surface or the app calls
GetDC. On the other hand Alexandre once said the software ddraw implementation
should use gdi for blitting instead of its own implementations, which means we
need a DIB section everywhere.

Either way it is a tricky situation and would need a lot of work. Honestly I'd
prefer to ignore it and let people force the video memory size lower. We cannot
limit the vidmem for apps using ddraw.dll in general because some opengl apps
use ddraw to figure out how much video memory the GPU has.

Yes. I think the problem is that wined3d can't read the color keyed surface
contents back. The game backs up the old content of the backbuffer before it
draws a sprite, and when it moves the sprite it draws the old contents back
rather than redrawing everything.
