This may be a old topic but i was looking a solution for the same problem and found a solution.
the problem may be caused like it was for me because i am using a 4k TV as a monitor so my desktop resolution its 3840 x 2160 (4k) but since that makes the text small i also have enabled in windows the option where it says ( Change the size of text, apps, and other items ) to the 175%, and i need to use like that if not i will not be able to read anything from my couch thats mainly the problem thats why MO2 interface text looks so big so to fix this just the app not all the other text you need to do this
in the exe of the app (and every other app want to fix this) right click and click on properties > Compatibility tab > Change High DPI Settings > High DPI scaling override > ( and choose " System )
click OK and relaunch the program and now the text will be ok at least that fix it for me
