Inside a NoMachine virtual desktop session it's not possible to maximize an application window only on one monitor. The window is always spanned across the available monitors, even when Resize remote screen and Fullscreen on all monitors are both set.

This problem occurred on the following environment:

- client with two FullHD monitors
- NoMachine server  v8 on Debian 11.1
- X11 vector graphics mode disabled on the server.

As a workaround, drag the window manually to nearly fullscreen size of one monitor.

Initial investigation shows it's affecting v8 and not version 7.
