This problem occurs with NoMachine Enterprise Client v8.8.1 running on a Windows 11 PC equipped with 2x24" monitors with 1920x1200 resolution in horizontal layout and NoMachine Cloud Server v8.8.1 on Red Hat 9. The virtual desktop (XFCE 4.16.0) is run on a node (Red Hat 9) with NoMachine Workstation v8.8.1 and equipped with 2x27" monitors with 2560x1440 resolution in horizontal layout. The same problem is reproducible also with connections to the physical display.

Steps to reproduce

1) Set the resolution of both monitors to 1920x1200 in the Display settings of the client
2) Select 'Resize Remote Display' and 'Fullscreen on all monitors': the virtual desktop is correctly displayed on both of the remote monitors.
3) Disconnect and reconnect the virtual desktop: However, after disconnecting the session, display settings are lost, and must be set manually.
