Description Dan Glastonbury 2023-11-15 22:49:21 PST

Bug 262774 introduced rendering for WebGL content over ARKit provided camera
feed using a CAMetalLayer hosted swap chain. It was intended that the
MTLSharedEvent active.completionEvent would be used to pace the frames and delay
the present until the frame has been rendered in the GPUP. This didn't work and
would lead to Metal preventing from processing our content for misbehaving.
