As I point out above, the problem exists. Granted, my screenshot was an unusual situation, where the part is zoomed in quite far, but since the artifacts on T-junctions are pseudo-random, they scale based on the total number of pixels that are in the scene that happen to lay on a boundary where T-junctions exist. So, if the above part were used repeatedly in a scene, but each one were quite small in the view, it's still likely that the T-junctions would lead to a similar number of incorrectly colored pixels. On average, the number of incorrectly colored pixels might be less than 1 (so none visible in many frames), but they would flicker into existence during animation.
