I'm writing a custom frontend for Mupen64Plus. I have overridden VidExt_GL_GetDefaultFramebuffer to use an FBO I create. It seems that GLideN64 will somehow override this FBO, resetting all of its attachments. If I try naively to setup the framebuffer again, it seems to be fairly inconsistent on whether it wants to work or not.
