Yet another bug with OpenGL

we have yet another bug with OpenGL...

1. 1. 1. 1. 1. 1. 1. 1. 1. 1. GL ERROR ##########
                              21:44:40 bcf @ Post render
                              21:44:40 bcf 1286: Invalid framebuffer operation

Also, adding more RAM increases lag. Lag is so insane that I can not move.

And, effects all versions.
