Something is wrong:

"Framebuffer error (unknown error), rendering will probably not work as expected
OpenGL error 1286 at bot beginDraw(): invalid framebuffer operation
OpenGL error 1286 at bot endDraw(): invalid framebuffer operation
Framebuffer error (unknown error), rendering will probably not work as expected
OpenGL error 1286 at top endDraw(): invalid framebuffer operation"

Somebody knows something about it???...
