To reproduce, connect to NoMachine server and leave it idle for the system to lock. Upon reconnection the mouse and keyboard input from NoMachine client will lag.
Additional info,
Client OS: Windows 10 Version 10.0.19042 Build 19042
Client NoMachine version: 7.6.2
Server OS: XUbuntu 20.04 with Xfce (V 4.14)
Server NoMachine version: 7.6.2
Also I am using display emulator to reduce the load on CPU.
Few tried remedies,
- Disconnect and reconnect.
- Restart the OS(works but not ideal)
- Close all application.
