Just my two cents,
About app slowness, I think it is related to the BMP generation... I noticed that the app seems to refresh only with some event (e.g. a touch on background).

I'm trying some stuff (e.g. BGRABitmap) and BGRAControls are much faster to redraw. Well, allways much slower than Windows, but much faster than "native".

Forcing repaint helps, but not enough.

Maybe using a faster bmp generation (like BGRA) could speed up everything.

Unluckily, my skill is not enough to help directly.

Regards,
Kjow

I, for one, gave up on it and just rewrote my gui in java...
