Date: Sun, 11 Sep 2005 14:41:07 +0300 (EEST) From: =?ISO-8859-1?Q?Martin_Storsj=F6?= <martin@martin.st> To: sdl@libsdl.org Subject: [SDL] [PATCH] Switching between fullscreen/windowed on OS X Hi, When switching from fullscreen to windowed mode for opengl applications, the current version of SDL sets an harmless error, regarding usage of a NULL semaphore. This is due to code which tries to shut down a blitting thread, which is only started for double buffered 2d video modes, not for opengl. The attached patch fixes this. // Martin
