Is there any hack to get the ptr and rowbytes to the OpenGL back buffer?

Typically, the back buffer is not even in memory you can access. You can get/set the buffer using Read/DrawPixels(), but depending on what you want, this will probably be too slow. ReadPixels() is mostly used for screenshots. What you should do very much depends on what effect you're trying to achieve...?

Cheers,
