I had to work-around this bug using devilspie. It seems to happen less frequently in 24.04 but it's still there. The desired behavior is to open on the same screen you start the application from.

What happened instead: Gnome-shell in Ubuntu 20.04 insists on placing new windows on the secondary monitor. Why this is a problem: My setup are Point of Sale terminals and the primary (a touchscreen) and secondary monitors are back to back. When the cashier presses the payment type button, the payment type pop-up is opening on the secondary screen which is displayed to the customer and not accessible to the cashier who needs to complete the transaction. The cashier can't move the pop-up on their own as there is no keyboard access (all buttons needed are in the application it self), and the touchscreen touches on itself (most of the time). In the past I was able to fix this with devilspie. As this problem has been around since Ubuntu 10.04. Was fine in Unity and 16.04/18.04 gnome-shell. But now devilspie is ignored by gnome-shell in 20.04 and gnome-shell keeps opening all the windows on the secondary screen. I've tried various gnome extensions and gnome-tweaks but none of them will open all windows (except the customer display) on the primary monitor only.
