    initial v1  
    33So one of the goals is to avoid unnecessary redraws, buffers in-between etc. This is how I noticed this bug, I presume SDL always initializes its screen surfaces but this is not the case of my backend (which just reuses the same shared memory buffer).

     5As I understand it, the "contract" is that what is not updated via copyRectTosScreen() doesn't need a redraw. And since BS1/BS2 doesn't do a full (640x480) redraw in the beginning, there are the aforementioned glitches present.

    57It's possible some other backend is also affects but it must be one of the more 'obscure' ones, which took a similar path as I did.
