It's the only effect I have and I do put it on each object individually.
If there are no other settings I should check, maybe it is working but too subtle for me to see.

Ah, tried a few more things but no noticeable difference. Off and On didn't see any noticeable difference. I'm not using opacity, color, or a 3D layer. No difference with 1/2 pixel coordinates, although I think the game turns all 1/2 coordinates to integers anyway? The object I am using this on is pretty large (a drawn portrait), though the example gif I see is for smaller objects, so maybe this isn't meant for larger objects.
