Window decorations, e.g., the minimise, maximise and close buttons are oversized

Sometimes when I turn on my laptop the window decorations are blown,


This only happens on/while connected to an external monitor whose resolution is lower than my laptop's which is 4K. I can fix it by changing the window decorations or window borders to something and back to what they were. This re-scales them correctly.

I have had this issue since I installed the OS. It is Ubuntu Mate 20.04.1 LTS with MATE Desktop Environment 1.24.0. The theme is Arch Dark. It is getting a little annoying having to toggle the decorations to scale them correctly, does anyone know how to fix them permanently?
