X11CompositorWidget needs to be updated or reimplemented for Wayland.
I tend to rename X11CompositorWidget to GtkCompositorWidget and handle both X11/Wayland there as it's implemented at https://github.com/stransky/gecko-dev

Bug 1425842 - Rename X11CompositorWidget to GtkCompositorWidget and implement WindowSurfaceWayland support,

https://reviewboard.mozilla.org/r/208202/#review214792

::: widget/gtk/WindowSurfaceProvider.cpp:60

mIsX11Display should be false all the time, maybe add assertion there.

::: widget/gtk/WindowSurfaceProvider.cpp:76

no need to use 'else' when returned line before.

Please add comment why this only applies for X11 display and what can be expected when on wayland backend

Please describe why you're crashing here.

Consider opening a new bug for unifying Initialize(nsWindow) for X11 and wayland.

As above, it would be cool of we have the same ...InitData for X and wayland.

I'll file follow up bug for that.
