No scaling of XWayland windows on second, non-scaled, display.
XWayland windows seem to only use the scale factor of the primary display, even after being moved to a second, non-scaled display.
In addition, after disconnecting a scaled display (thereby switching the primary display to the non-scaled display), XWayland windows will still be scaled (with the notable exception of Chrome, which will scale correctly, but still display a 2x scaled mouse pointer once it hovers over the XWayland windows).
Is this even a gnome-shell bug, or something related to Wayland?
