 I forgot that was there hihi.  It was used to easily size LOGic to shoot videos back in the old days.
On Win 10 (and probably most other versions), right-click the desktop. Under SCALE AND LAYOUT, look for CHANGE SIZE OF TEXT, APPS, AND OTHER ITEMS.  This is basically a system-wide zoom control.  See what it is set to, and go to a smaller number.
