I have installed NoMachine 7.6.2 on Ubuntu 21.04 with Wayland compositor. After the install the physical screen started to blink. When Wayland is enabled I get a lot of these messages:

The only solution is to shutdown nxserver.
sudo /etc/NX/nxserver –shutdown
There is no problem when X11 is enabled. Is there any parameter I should enable to stop preventing this when Wayland is enabled?
