Initially I didn't see the issue since my system was using the default text setting, Arial, 9pt(.125", 3.175mm). If I increase the font size to something higher, like 12pt, then some numbers are smaller but it seems inconsistent. I just went thru several size changes from 10 to 12 pt and the numbers weren't affected.
One other thing I am seeing is the dimension line running into the dimension text, if I turn off Equations then the overlap is reduced:
If I adjust the spacing in Spacing Control to, in this case, 6 mm then it looks okay but the spacing is not even on both sides
_O
If I turn on Legacy mode it's not a problem.
I've turned in a ticket on this one already. Hopefully there is a fix.
