Please upload the result of `xrandr --verbose` on the system when the issue can be reproduced. It would be even better if you could build a VM image showing the issue so I can look into it on my side.

VM image is a bit tricky. And most VM managers don't let you disconnect virtual monitor, as far as I know.
