In Ubuntu-Budgie the above trick doesn't solve the problem. I notice that Ubuntu Desktop is using gdm3 whereas Ubuntu Budgie is using lightdm. They are calling xorg with different arguments. So I reconfigured Budgie for gdm3 and, after creating the monitor.xml file, the flicker is gone.
I hope, this helps to fix the problem in Budgie. Let me know, if I can do something else.

Makes it a very unpleasant experience, if not renders it unusable. If switched to only single screen, cursor is completely stable. When issuing xrandr --output HDMI-2 --scale 0.99x0.99 again cursor is stable. Switching to 200% scaling in the desktop settings, doesn't help. I tried to catch the effect in a movie. However, because of frame rate, it is not possible to show the effect. If if its helpful, let me know and I'll try harder.
