[PyOpenGL-Users] glGetInteger with GL_READ_FRAMEBUFFER_BINDING

[Ákos T. <dxm...@gm...>]

While trying to get the currently bound read buffer, I encountered the
following error:

  File "/home/marquesas/PycharmProjects/pygrafjatek/pyge/buffer.py", line
56, in blit
    previous = glGetInteger(GL_READ_FRAMEBUFFER_BINDING)

This is exclusive to GL_READ_FRAMEBUFFER_BINDING; trying to read
GL_DRAW_FRAMEBUFFER_BINDING works.
