Solved Adjusted system DPI, now certain things aren't scaling back right?

[Emcee]

To combat some missing icons (specifically, MSI Afterburner) I adjusted the system DPI to 125% then back to 100%. Most everything went back to normal, except two things:

1. Firefox's menu and toolbar font size
2. System message font size

Restarting does nothing. I tried changing to 150% then back to see if that'd work, but now it's even smaller! Programs seem fine, I tested Word and Skyrim. 1920x1080 res if it matters.

How do I fix those issues?

Thanks in advance, and sorry if this has been covered. I couldn't find any relevant threads, but I might be searching the wrong terms.

EDIT: Looks like the menus for Media Player Classic are tiny, too.

Ok, don't know why I didn't try this before, but the settings are tied to the current theme, so switching it fixes the problem.
