I should add that I only reproduce this when screen B is set to the primary screen. This can be reproduced on x11.
I'm able to reproduce this on both X11 and Wayland on git-master There is additional buggy behavior when trying to make B not a replica of A Display Configuration: External monitor on top of laptop display 1. Set external monitor to be a replica of the laptop display, click Apply, Keep 2. For the external monitor, change Replica of to None Result: Apply button isn't active - bug It isn't possible to rearrange the screen positions - bug 3. Disable, then re-enable the external monitor, don't click Apply yet Result: The external monitor is positioned on top of the laptop display. It's necessary to move it to the desired position, otherwise the displays will overlap. - bug
