When my game starts, it opens up a new full-screen window, then changes screen resolution. At this point the screen goes black as expected, but then the Windows desktop redraws itself slowly at the new resolution (taking two or three seconds) before the screen blacks out again and the game continues. I've tried inserting UpdateWindow() and ShowWindow() calls immediately after the mode change, but can't get rid of the irritating desktop redraw. Any suggestions?
