I recently updated my project to v50 Integration and suddenly my Ray functionalities became broken. I removed all assets from my scene thinking it was something that I had broken until I thought to try the Ray Examples scene from Interaction SDK which I now realise is also broken (v49 worked just fine in the examples and in my project).
To replicate - try and move around in the scene especially looking backwards in the scene away from from where the canvases are and you will see very bad freezing and glitching of the camera.
FYI this is Quest standalone issue only. Seems to work fine on PCVR. On further experimentation it seems to be affected by the boundary on ground which is strange. If the boundary is visible then the camera doesnt glitch and scene works fine. If Boundary is not visible then camera glitches and freezes as soon as you try to move away from the canvases in scene
