When running in a Wayland environment, webkitgtk needs the libwpe backend to implement accelerated compositing on Wayland. Without this, you can get errors like:
Webkitgtk is supposed to gracefully disable AC when this happens, but this doesn't appear to be working for me. You can manually disable AC with WEBKIT_DISABLE_COMPOSITING_MODE=1.
See https://gitweb.gentoo.org/repo/gentoo.git/tree/net-libs/webkit-gtk/webkit-gtk-2.28.4.ebuild#n222 for some idea of how Gentoo handles this. In nixpkgs, I think it's a good idea to just provide libwpe everywhere, regardless of whether the user has configured "wayland" or not.
