gnome-shell (clutter) on EGLDevice

Sorry if this is incorrect list. I'm trying to debug why my Gnome fallbacks to X11. All I get is cryptic message:

Aug 07 00:33:32 babylon5 gnome-shell[3616]: g_strsplit: assertion 'string != NULL' failed
Aug 07 00:33:32 babylon5 gnome-shell[3616]: g_strsplit: assertion 'string != NULL' failed
Aug 07 00:33:32 babylon5 gnome-shell[3616]: Unable to initialize Clutter: Unable to initialize the Clutter backend: no available drivers found.
Aug 07 00:33:32 babylon5 gnome-shell[3616]: Unable to initialize Clutter.

Does anyone knows what the problem might be (I tried to gdb into gnome-shell but it hanged terminal)?

PS. Is attaching display to dGPU with EGLDevice while GEM/iGPU drives primary display meant to work? I see primary display blinking but that's it.
