Two possibilities come to mind. The red channel in each pixel might be at the left, causing all the pure red text to be slightly shifted relative to the other text.

Another might be chromatic aberration if you wear glasses. (This causes the Windows logo to look comically maligned for me.) Whether it's behind or in front of the text would depend on the tilt of your head.

Wow I posted at basically the same time, and also mentioned the Microsoft logo. It's just a perfect test case to see this kind of thing happening, I guess.
