Date: Thu, 28 Feb 2008 22:54:29 +0100 From: Sylvain Beucler Subject: [SDL] SDL window resize and flicker I have a resizable SDL window, and when it's resized, the surface goes black _and_ is flushed to screen before I have a chance to redraw it. This causes flicker. The super-small attached patch fixes this issue by avoiding a SDL_Flip() right after the window resize. What do you think? This SDL_ClearSurface function is only called once in the code, in SDL_SetVideoMode, and as far as I can tell the patch doesn't introduce other changes than getting rid of the flicker.
