OpenGL extension MESA.copy_sub_buffer
This module customises the behaviour of the OpenGL.raw.GLX.MESA.copy_sub_buffer to provide a more Python-friendly API
Overview (from the spec)
The glxCopySubBufferMESA() function copies a rectangular region of the back color buffer to the front color buffer. This can be used to quickly repaint 3D windows in response to expose events when the back color buffer cannot be damaged by other windows.
