Did not work with Arc. Also, it is very weird that it works correctly when I launch gnome-system-monitor as another user from the terminal, as specified in the question from the link.

Anyone else running the Cinnamon DE is having an issue where Gnome System Monitor's menu (on the top left) appears as text?

Nope. The theme just isn't updated for the latest gtk. You could try installing Arc; it works correctly.
