Q: App Background Colors Are No Longer Uniform
Ever since upgrading to Sierra, both Chrome web pages, and Atom code editor backgrounds are messed up. For example, in Atom it looks as though I've highlighted all the text, some of the background is dark and some of it is lighter. In Chrome, Facebook's blueish grey background will be uniform, and then get lighter on the sides abruptly. This abrupt change happens on other colors as well, making it look as though I've selected certain parts of the page with my cursor. Basically the uniform color of the backgrounds on certain webpages or apps (i.e. Atom and Chrome) are no longer uniform.
This background change only happens when I plug my HDMI cable into an external monitor. If I am working on just my macbook pro retina screen, everything looks fine. If I plug in my HDMI cable to an external monitor, the backgrounds become non-uniform, even on the macbook pro screen (when mirroring). I used the HDMI cable and monitor with a different computer, and the problem does not exist, so I think it has something to do with macOS Sierra. Weird thing is, this problem only occurs with Atom and Chrome. Safari, for example, is absolutely fine.

Before uninstalling those apps, be sure to do a Time Machine backup:
