[arch-general] gnome-system-monitor on Cinnamon - menu shown as text instead of icon and style broken

[Marcelo "Marc" Ranolfi via arch-general]

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

I've added some images here: https://unix.stackexchange.com/q/436635/154671
