The GNOME-shell freezes when  EGL capture and Wayland are enabled.

This problem has been reported on Ubuntu 22.04, but can occur on other Linux distributions with Wayland-enabled desktops.

As a workaround, run the following command to disable EGL capture:
$ sudo /usr/NX/bin/nxserver --eglcapture no

This will set the following key in node.cfg:
EnableEGLCapture 0

(note that since v8 EnableEGLCapture is enabled by default. In v7 it is instead disabled).

Otherwise disable Wayland and keep EGL Capture enabled.
