I am also having the problem of ‘smudging’ as you put it… But i found a workaround for that – move the camera slightly and then move it back to where it should be. For some reason the second time it renders the text in the exact same position on the screen, it looks a million times better. I am neck deep in development so i don’t have time to debug from a clean project. I just wanted to offer my workaround… 1/2 a second after your camera settles into place, do a SetActorRotation and move it a couple units in any direction, and then back into place.
Good luck!
