I restarted my computer, and afterwards I immediately noticed that some fonts on some websites are now rendering darker. I did manage to find a screenshot before and made a screenshot of how it displays now.. here's a letter to show the difference:
Notice the after is darker. I'm half way through creating my own font, and I wonder if something I did in fontforge has created the problem? Or if it is something else? Either way, how do I get it back to how it was? I'm at the point of wanting to reformat!
