Bug#1121628: Bug: XWayland scaling is broken in Testing

[Jeremy Bícha]

Control: reassign -1 src:systemd 258.1-2

I can reproduce this issue in Debian Testing, but I can't reproduce
this issue after downgrading systemd back to 258.1-2.

See also the upstream GNOME issue:
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/8866

Test Case
=======
Ideally, you'd have a HD display (1920x1080 or higher)
Open the GNOME Settings app.
Switch to the Displays tab and set Scale to 200%. Click Apply then
Keep Settings.
Close the GNOME Settings app.
Run GDK_BACKEND=x11 gnome-text-editor

gnome-text-editor should be scaled the same way as your other apps.

Thank you,
Jeremy Bícha
