Wierd shifted colors and unsatisfactory GL_Context

Hello everybody, I have problems setting SDL_GL_SetAttribute. I have written an app for Android, which runs well on almost all devices ( startscreen see figure 1). On some devices I have the problem that the colors are shifted (see figure 2). It turned out that in the GL context, the pixel format is RGB444 instead of the desired RGB888. So I have despite my SDL_GL_SetAttribute default RGB888 received only RGB444. As far as logical, the device obviously canât give more !?. (Samsung SIII GT-I9300 - should be able for RGB888 ) figure1: [Image: http://editionchamaeleon.de/figures/2.jpg ] figure 2: [Image: http://editionchamaeleon.de/figures/1.jpg ] Now comes the wierd part: If I delete SDL_Window, SDL_Renderer and GL_Context (SDL_DestroyRenderer, SDL_GL_DeleteContext, SDL_DestroyWindow) and simply recreate it directly in the same thread ( order: SetSDLAttributes, SDL_CreateWindow, SDL_GL_CreateContext, SDL_CreateRenderer), I suddenly get a correct graphics output (picture 1) and SDL_GL_SetAttribute RGB888. What did I do wrong? Something with the order of the calls? I would really like to solve this a little more elegant than creating an SDL_Window, a GL_Context and a SDL_Renderer, then destroy it and recreate it right away. Especially because there are other end devices that seem to have a problem and crash. _______________________________________________ SDL mailing list [email protected] http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org
