     1.7 + OpenGL problems

     1.9 +
    1.10 +If you have desktop OpenGL headers installed at build time in your RPi or cross 
    1.11 +compilation environment, support for it will be built in. However, the chipset 
    1.12 +does not actually have support for it, which causes issues in certain SDL apps 
    1.13 +since the presence of OpenGL support supersedes the ES/ES2 variants.
    1.14 +The workaround is to disable OpenGL at configuration time:
    1.15 +
    1.16 +    ./configure --disable-video-opengl
    1.17 +
    1.18 +Or if the application uses the Render functions, you can use the SDL_RENDER_DRIVER
    1.19 +environment variable:
    1.20 +
    1.21 +    export SDL_RENDER_DRIVER=opengles2
