A known issue[1] exists when running RaySession on Wayland. 
Once started in a terminal, there will be an error message that
reads "qt.qpa.wayland: Wayland does not support QWindow::requestActivate()"
which obfuscates numerous other messages that are printed to the terminal.
In the QT Forum this was discussed[2]
with the result that using this function call is not allowed
in wayland.

As such, running RaySession on Wayland is not recommended until the issue
can be fixed upstream.
