You may have accidentally zoomed in or out a small percentage, which in return makes the fonts appear slightly different.
To fix the issue, hold the 'Ctrl' key, and scroll your mouse wheel up and down, or hold 'Ctrl' and press the plus or minus signs on your keyboard.
Additionally you could have an add-on for the browser of choice which changes d2jsp's font, so you might want to check that.
