Hello!

I can reproduce this too, but I have a workaround.
In Advanced in the Display configuration for dom0:

  • Configure the screens to your liking (In General)
  • Add a profile
  • Enable Configure new displays when connected
  • Enable `Automatically enable profiles when new display is connected

For reference, these are my settings: display
After connecting the displays again, I do not get any popups in any DomUs, only dom0.
