	Hi,
I'm sorry, I do not have much idea, I do not recall seeing this before.

The `--display` option is more for the X11 and it does not propagate
down to the WebKitGTK. It's left for backward compatibility, sort of.
I guess the system/environment variables are not set properly, thus it
confuses the gtk3 (and eventually WebKitGTK). My Wayland GNOME session
has set these DISPLAY-related variables in the system:

    $ set | grep DISP
    DISPLAY=:0
    GNOME_SETUP_DISPLAY=:1
    WAYLAND_DISPLAY=wayland-0

Maybe there's missing xorg-x11-server-Xwayland?

In any case, this is lower in the stack, not in the Evolution itself,
I'm afraid. If a gtk3-demo works properly, then maybe your distro
builds with clutter, then it could be something with it, but I'm only
plain guessing here.

If switching from Wayland to X11 would work, then consider it as a
workaround.

	Bye,
	Milan
