Wrong. When I disable EFB copies, the blurry-edge problem is still present, even after the bloom is gone. (along with overly dark everything, and that black box in the corner.
I think the reason AutoIR is buggy is because it is a hack designed to work with all IRs and has some off-by-one errors, et cetera, that cause the bloom to be copied from too high, or rendered too low. The blur pass stretches the glitch line into a fringe of glitchiness across the top of the screen.
That does not explain why 3xIR has that weird blurring effect that I think results from rendering then stretching to my screen resolution, meaning it's rendered at the wrong resolution. Does Mario Kart Wii have any trickery that renders the image at a reduced resolution then stretches it somehow?
Edit: By the colors of the road, it is clear that the 3x is internally rendered at a different resolution, but whether 3xIR is greater than or less than 1920x1080, I can't figure out.
