Massive fonts after upgrade. CSS files unchanged. Why?

[thenameiwantedwastaken]

I just upgraded to 2.8.0. After the upgrade, all fonts are really huge - taking up almost the entire screen. I didn’t change any of the style sheets for font sizes. What could have caused this to happen?

Further info:

This is a screen resolution issue. Something about the update has changed my screen resolution to much lower (1024x768) than what it was before. I don’t think that’s specifically a Magic Mirror issue, but as I updated Rasbian before the MM update that may have changed something. I have not been able to figure out how to get back to how it was before.
