rdesktop does not keep screen refreshed unless the window is active and there are keyboard or mouse inputs

[motorious1]

1. establish rdp session via rdesktop to a machine with command: 'rdesktop -P -z IPaddress:PORT &'
2. Change focus to another window and have rdesktop window in background on second monitor

Tried:
"-b" option instead of "-P" no change in behavior
tried with no switches, no change in behavior
leaving rdesktop window active, if there are no mouse movement or keyboard strokes after sometime, the rdesktop window does not automatically refresh the screen, I would expect -b or -P to remedy this...

Problem: rdesktop screen does not refresh automatically, have to move mouse cursor or make rdesktop window the only active window

I don't know if the issue is at the OS (using Debian based distro), or the remote OS rdping into (Windows 10) or if that's just the way rdesktop is designed possibly to save system resources (I have plenty so not worried about that aspect). If it's by design, then maybe this needs to be a feature.

Appreciate any help anyone can provide. TIA!

Any update about this issue? Its happening with me as well.

Update: In my case, the server was configured to turn off screen after 5 mins of inactivity. I have set the machine to never turn off screen and it fixed the issue for me.
