Photoshop 2020 window keeps resizing (going off screen) after switching to other applications
I'm using Ps 2020 on a Mac (Mojave 10.14.6)
After I switch to other applications and return to Ps 2020 the window has gone slightly off screen.
To re-center the Ps application requires clicking inside Ps to "wake it up" and centre itself.
See the entire screen, screenshot below.

Clicking the color swatch (for example) re-centers the screen but its annoying having to do that every time.
Is this happening to anyone else?
Please note: I'm not using Photoshop Elements. I'm using Photoshop (Ps) 2020
