Under System Setings -> Display and Monitor -> Display -> Scale Display. If I change it from 1, when I want to reset to 1, it will behave as a 2. I can see that changing here, seems to be the same as changing SS -> Fonts -> Force fonts DPI. It will be enabled and changed to a 96 factor (192 in 2x). When I go back to 1x, this option will be unchecked and the default should be 96, which is not applied. I have to force 96 dpi in order to get what I had in the first place.
Did you set a non-default value in SS -> Fonts -> Force fonts DPI?
