Hello,
I use NoMachine server on a Debian 13 server (9.2.18) and NoMachine client on Windows workstation. After upgrading the windows client from 9.0.188 9.2.18, I have two black bars on each side of screen :
With 9.2.18 :

With 9.0.188

I did not change anything in options, I always use “Scale To Window”

Kindly note that this problem only depends on Windows version, if I use NoMachine 9.0 on Windows and server 9.2.18 on Debian it works perfectly, no black bars. The Desktop used on Debian server is xfce.
I’ve tested last version of Windows client on Windows 10/11 , same observation.
