Charles is spot on here Steve. Open both images and compare the top of the “L and V” to each other too. In the image from V5 it looks correct, but in the one from V6 it looks like a “banana”. The “A” pops the other way and the “X” has rounded feet… and for designers that rely on visual evaluation then that just isn’t good since it appears that the curves are wrong. (and the thing that causes these out of place pixles (Just like Charles points out with the “T”) are probably (?) the same thing that causes other strange linedrawing artifacts.)
That said, I agree with you that the V6 image looks better as a first impression!
