Describe the bug

It might be hard to replicate, given the environment. However, given that the connection to the remote host is a shadow connection, AFAIU under no circumstances should the client decide the display characteristics of the remote host (Analysis, DPI, Scaling, etc)

Server is a one-monitor, Full HD laptop. Client, however, is more complicated:

$ xrandr | grep -P '^\S|\*'
Screen 0: minimum 320 x 200, current 4480 x 1440, maximum 16384 x 16384
eDP-1 connected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)
DP-3 connected 1920x1080+2560+0 (normal left inverted right x axis y axis) 510mm x 290mm
   1920x1080     60.00*+  50.00    59.94  
DP-3-8 disconnected (normal left inverted right x axis y axis)
DP-3-1 disconnected (normal left inverted right x axis y axis)
DP-3-1-8 disconnected (normal left inverted right x axis y axis)
DP-3-1-1 disconnected (normal left inverted right x axis y axis)
DVI-I-5-4 disconnected (normal left inverted right x axis y axis)
DVI-I-4-3 disconnected (normal left inverted right x axis y axis)
DVI-I-3-2 disconnected (normal left inverted right x axis y axis)
DVI-I-2-1 connected primary 2560x1440+0+0 (normal left inverted right x axis y axis) 697mm x 392mm
   2560x1440    144.00*+ 120.00    99.95    59.95

In addition to that, the client is connected via DisplayLink to the displays above - and the lid is closed (eDP-1 connected, but no selected modes).

I am suspecting that during the client's "Alt+F2, r" sequence, the xrandr state might revert first to eDP-1, full-hd and then come back to the mode above.

Somehow between the start and the end of the "Alt+F2, r" sequence, the server is instructed to switch to 4480x1440, at 200% scale (among DPI changes which I cannot find in gnome-settings.
