Black screen issue when using NoMachine for gaming and applications

[NebuchOwl]

Hello,

I am currently facing an issue with NoMachine while using it to connect to another computer over LAN. The problem occurs when I try to launch games or certain applications. Specifically, the screen turns completely black when the games or applications start.

To troubleshoot the issue, I made the following changes to the node.cfg file:

1. Added DisplayServerExtraOptions "-nodxgigrab".
2. Changed #EnableScreenBlankingEffect to EnableScreenBlankingEffect 0.

While these changes seemed to help with the black screen issue in games, they introduced another problem. Some applications, like NetLimiter, now appear with a black screen instead of their normal interface. I have attached screenshots showing both issues for reference:

• Screenshot 1: Black screen when launching a game.
• Screenshot 2: Black screen in the NetLimiter application.

I would appreciate your guidance on how to resolve this problem. Are there additional configurations or steps I should try to fix both issues?

The screenshots were not attached. Can you submit them again?

It would also be useful to know more about:

OS and version on the side you are connecting from (client)
OS and version of the side you are connecting to (server)

Thanks.
