Steps to reproduce

In Summary, when you open a multi-monitor full-screen remote connection to xrdp 0.10, it's not possible to minimize and then maximize correctly the remote desktop connection: only one monitor is displayed when you maximize. The same workflow works correctly with xrdp 0.9.

Equipment utilized:

• laptop running Windows 11, screen resolution: 1920x1080 (probably irrelevant)
• external monitor, screen resolution: 1920x1080 (probably irrelevant)
• external monitor is configured to extend (not mirror) the laptop's display
• the remote Linux desktop is configured with i3 because i3 makes it very easy to identify monitors and desktops by number, but the issue also affects GNOME

Reproducer:

• open Remote Desktop Connection on the Windows 11 laptop
• select "Use all my monitors for the remote session" in the Display tab
• also select "Display the connection bar when I use the full screen"
• connect to a Linux machine where xrdp is installed
  • you should now see a full-screen xrdp connection on two monitors which works as expected
• in the Remote Desktop Connection bar, click the "Restore Down Button"
  • the resulting window correctly encapsulates the multi-monitor configuration, i.e. using the scrollbars it's possible to see both monitors contained in the Remote Desktop Connection Window
• click the Maximize button in the Remote Desktop Connection Window

✔️ Expected Behavior

• xrdp 0.9 has the expected behavior:
  • the window is restored full-screen to both monitors
  • you can see the remote desktop connection again on two monitors in full screen

❌ Actual Behavior

• v0.10 behaves incorrecly:
  • the windows is restored full-screen to one-monitor only
  • the monitor you see depends on your desktop environment, but it's only one
    • for instance, with i3, if you had Desktop 1 and Desktop 2, now you can only see an empty Desktop 3 which didn't exist before, and the status bar does not show indicators for Desktop 1 and Desktop 2 anymore
    • GNOME's behavior is more difficult to understand/predict because it's doesn't have the same way of numbering and identifying desktops uniquely
  • however the output of xrandr still shows two connected monitors, which seems correct

Anything else?

The workaround is to disconnect and reconnect, and the monitors are once again displayed correctly.
