Image is drawn one frame too early #6

This causes overlay to be out of sync with image data. May also be the cause of crashes on newer PyOpenGL

Solved by holding the old texture ID for some extra frames, akin to double buffering. Crashes were a separate issue caused by glGenTextures returning np.int32 instead of int.
