Remote access recommendations

Hi Friendos,

I am looking for recommendations for remote access software to access my server and see its GUI. The server is running Ubuntu 23.04 with KDE Plasma. I chose 23.04 as I have an Intel ARC card in there.

The machine that will be accessing runs Arch Linux with KDE Plasma and an nvidia 4080.

I have tried VNC but can't stand the latency, and up until now have been using NoMachine but for some reason I am getting some quirk where the mouse will get stuck in a left click state and my only way to get out of it is to reboot the machine (not ideal for a server).

Any recommendations on what to use, or how to fix my problem would be greatly appreciated.

EDIT: I forgot to mention, I'm happy with Lan only options too, as that is where I do 90% of the management from
