FlatColor theme combo box glitching out

It's not very evident from the GIF (zooming in might help) but the FlatColor combo box glitches out on Gnome Shell v3.36. (This doesn't happen with any other themes)

Could you open that program from console and paste the output, sometimes helpful messages on what's wrong with a GTK theme show up there.

This shows up on all apps that use GTK. No additional output upon clicking menus.

I've seen that happen when you switch between GTK+ Themes.

I've checked these lines but I don't seem to be able to find anything irregular about them 🤔

I have the exact same problem. Really annoying bug tbh.
