Could you attach a log with WINEDEBUG=+timestamp,+pid,+loaddll,+system,+x11drv,+event,+win?
Attached.
I'm using a dual monitor setup every day and I don't experience any problem.
I suspect it may be hardware/driver related. I'm using a laptop with a usb-c external monitor plugged into a usb-c hub.
To get it to work on debian, I had to install the displaylink driver from Synaptics (https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu).
