Terminator not showing up on alt+tab or in menu bar

[devonestes]

Cinnamon crashed for me yesterday. I rebooted and everything seemed OK, except Terminator no longer shows up either when I alt+tab, or in the menu bar. It still works if I click on the window, but if it's minimized there's no way to bring it back again. Aside from this wierdness, it's a fully functioning shell.

This is only happening with Terminator, and it always happens. I used Timeshift to restore to yesterday's settings, and it still isn't showing up, which is SUPER weird, so it doesn't seem to be a settings issue. I also removed Terminator with `sudo apt-get --purge remove terminator` and reinstalled it, still seeing this problem, so I don't think it's an issue with Terminator.

Here's an image showing the issue:

I'm going to try a clean install of Mint to see if that solves it, but I'd be curious if anyone has any idea what this might be.
