--- Comment #13 from Brian tehstealth@yahoo.com 2009-07-03 18:35:17 --- Forgot to mention, the error changed a bit, it looks like this now:
fixme:d3d:stretch_rect_fbo >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION (0x502) from glBlitFramebuffer() @ device.c / 6523
and like I said, only happens occasionally, now it's not spitting continuously into the terminal.
