UE 5.5.0 v72 Battery Saver mode causes one eye to go completely blank

I released my game about a week ago on the Meta Horizon store, and I got some feedback from a couple players that battery saver mode causes the entire left eye to go completely black.

I can fix this by enabling mobile multiview, but mobile multiview causes my stereo layers to render at the incorrect depth (they appear to be floating off of the surfaces they're supposed to be on)

Does anyone have a solution to this that doesn't involve mobile multi-view? Or is it just an unfixable engine/headset bug?
