My Ubuntu 20.04 laptop is attached to a 2K external monitor. Whenever I reboot or logout (this issue began recently), the menu bar is being scaled. To revert back to the normal scaling, I have to set the system scaling to 200%, apply, and then back to 100%, apply. Please see the attached screenshots comparing this.
200% and back to 100%:
Why is this happening and what can I do to fix it?
