Date: Wed, 23 May 2007 00:39:47 +0300 From: "Eyal Lotem" To: "SDL Mailing List" <sdl@lists.libsdl.org> Subject: [SDL] Bug in GL_SWAP_CONTROL extension name. The checked extension name is incorrect. The attached patch fixes it to the correct name. I don't think that under any setup, this extension name was ever correct, which is why its not OR'd against the old check. This fixes the "tear effect" (vsync problems) I had here with nVidia GLX drivers. Eyal
