Yes it’s fixed for me with stationary lights, but still gives problems with movable lights. If you change the directional light in the 5.4 VR template to movable it still gives buggy shadows in one of the eyes. Didn’t happened in 5.3. And apparently it’s still not solved in 5.5 preview (comments in the bug report liked avobe) (update: I’ve just seen in that page that you’re already aware of it).
I’m using Meta Quest Link as OpenXR runtime.
