--- Comment #1 from Michael Catanzaro <mcatanzaro at igalia.com> ---
This is with the fdo backend. It's possible that this is a fdo backend bug, because the mesa backend calls wpe_renderer_backend_egl_target_dispatch_frame_complete() inside its wpe_renderer_backend_egl_target_interface::frame_rendered callback, and that's called by AcceleratedSurfaceWPE::didRenderFrame. I'm not sure if that's called on the main RunLoop or not. But the fdo backend calls wpe_renderer_backend_egl_target_dispatch_frame_complete() inside its wl_callback_listener::done callback, which is wrong because that's called on the main RunLoop.
