Hold up!!! found something. It was after the last update for me
Then set icons back to original size if you changed them
I haven't checked everything but this is better
Tested on a Surface book with default screen resolution 3000 x 2000
Found out fixing notebook++ which was having the teeny-tinies as well. Fonts stayed the same but icon scrunchies seem gone. The figure doesn't do it justice, but if you get the flakies on other applications experiencing this, then give this procedure a shot.
