These fonts are so big and ugly. The only thing I can think of that could have caused this is: The other day some of my desktop icons were the placeholder white page, I used "Windows Shortcut Arrow Editor" (x64) to change to classic shortcut arrows and then back again, which repaired my icons. Then this happened.

Also, if I mouse over one of these links, the blue underline is broken where the bolded text is.
The only other things I can think might be affecting this are possibly Stardocks's Fences, Start8, or ModernMix apps, though I doubt it as they've been on this PC for weeks at least. Also, I do have the DPI and ClearType set up already. This just began occurring out of the blue. I also tried resetting font settings to default both in Chrome and the Control Panel.
