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.
