On Apple silicon, rendering is done on a separate node, so do not limit selection of the render node to the display device in case the display device does not have rendering.

Oh ok so you skip the first drmDevicesEqual xD
I think the problem is how we handle https://wayland.app/protocols/wayland-protocols/432#zwp_linux_dmabuf_feedback_v1:event:tranche_target_device. (Probably)
It would be better to fix that.
