Seeing squiggly black border of passthrough sight when pIaying in-Editor via AirLink

When I play in-editor with VR preview through AirLink with Unreal Engine 5.1,

I see a squiggly line on the border of the pass-through field of view, and a black surface is also visible beyond that line.

Every time I turn my head and look, the border disappears one beat later, and remotely rendered virtual objects are also drawn one beat later in Meta Quest 3.
