I am trying to set the settings on Display Fusion and the font size is HUGE. I have attached a screen shot. I also have display scaling set to 100% so there is no scaling going on. You can see the menu from the system tray is fine, but the clock and the app font size are huuuuuuge!

FYI a reboot fixed it. Typically a log off and log on is supposed to set the scaling for everything but in this case I had to do a full reboot.
