Here is a playground where the issue repros, only on VR. The text block is displayed correctly when looking at one half of the dome, while it renders incorrectly when looking at the other half of the dome.

On VR, the message ‘Can you read me now?’ should be displayed properly for every camera degree
We starting seeing this issue when we updated from 4.2.0-alpha.2 to 4.2.0-alpha.20.
On the playground example, the distance for the box and 2 planes from the camera is very clear and the order is correct at every moment. However the rendering doesn’t seem to be working as expected. On half of the dome, the menu renders correctly and on the other half, it doesn’t.
