Possible small buglet in SDL on NT

SDL Development

When you change the size of the video surface to a smaller size in
windowed mode, Windows NT leaves garbage behind on the screen area
that you used to use.

I don’t know if 98 does the same, my app crashes on 98 :frowning:

Yeah, I don’t know how to fix this one. Suggestions?

SetWindowPos doesn’t invalidate the exposed areas, you need to do that
manually so that the windows underneath will repaint. You can do it the easy
way and add a single InvalidateRect(NULL,NULL,TRUE) after SetWindowPos to
tell everybody to repaint everything :slight_smile:

Cool, can you apply that change to the latest CVS and test it so I
can get a patch? I don’t have a windows system in front of me. :slight_smile:
