Oculus OVR Gaze Point doesn't aim right after adding second camera for UI

Hello, I'm doing an Oculus Quest game project part of my master degree.

Initially, I had a problem with my World Space Ui Canvas. Indeed, some particle effects and others were in front of my pause menu canvas. To avoid this, I had a new camera (child of the other). The settings for the 2 cameras are below.

Adding this camera solves my initial problem, but now the Gaze Pointer doesn't aim right anymore. It's like it was influenced by me movement of the view.

At the moment I've decide to stay with my original camera with some effect in front of it. But I wish I could change to UI_Camera for my submission.

Can someone help me ?

Thanks,

:oliv'

Here are my different settings:

edit : I forgot to add my Canvas Setings
