5.6.6 to 2019.2 Linux App won't move to 2nd screen

Long story but now on subscription so updating our project. Did the upgrade to 2018.1 to convert text mesh pro then to 2019.2 to be current.

Our app runs on a kiosk that has front and back screens. We run the same application as two instances, one for each screen. The base system is ubuntu 14.04 as a minimal install, no Linux desktop, but both screens as one X session that is 3840x1080. We launch the back screen app then use xdotool to move it to 1920x0 which is where the back screen is located. Then the front screen app is launched at 0x0.

Under 5.x.x this has been working fine. With 2018.1 and 2019.2 it seems the multi-monitor stuff is getting in the way. In trying to move the back app I can get it move around on screen 1, but it never even partially shows on screen 2. If use the mulit-monitor functions and activate the 2nd display I can get things displayed there.

If there a way to turn this off? I just want to move the app to a screen coordinate and have it display with out trying to out smart me.
