I have AX 2012 R2. Sometimes the font size enlarges on some windows. If I close and reopen the form it corrects itself.
One time I didn't have my hand on the keyboard or the mouse, I was just looking at screen, and the form refreshed and the font size increased (that was a one-time occurrence; usually it doesn't change once the form has opened).
This is quite random and can happen to any form. I'm not sure if it's the actual font or just the font size. Please see screenshots below.
Has anyone else seen this before and any ideas why this happens?
