A very important detail:
Ubuntu builds webkit2gtk with -DUSE_WPE_RENDERER=OFF
This was done because we would need Ubuntu Security Team sign off to get wpewebkit in to Ubuntu's 'main' archive section instead of in 'universe'.
It looks like this bug is specific to that config.
"The issue is that WebKitGTK's internal Wayland compositor needs to implement zwp_linux_dmabuf_v1 rather than relying on EGL_WL_bind_wayland_display.
In the meantime, we could revert the part which makes us strictly rely on dmabuf on the Mesa client side, and keep both in parallel for a little bit. But WebKitGTK should really be implementing this interface."
