To reproduce:
1. Open attached project "QuestJitter.zip"
2. Build and run for Oculus Quest
3. While in application, observe the moving object

Result: the object is jittering resulting in blur-like graphical artifacts

Not reproduced in: 2017.4.29f1, 2018.3.14f1, 2018.4.1f1,2019.1.0a15

    Same here on Quest, Unity 2019.1.7f1.

    72 fps, head tracking is smooth, controllers tracking is mooth, but every object moved by code in the Update method (with time.deltaTime) is jittering.

    Experiencing the same problem on 2019.1.9f1 with a relatively simple scene. If I grab an object and I move my head quickly the movement looks quite jitty. Strangely, it seems affecting more the objects than the local avatar hands which are more fluid.

    Hi, is there an ETA for this fix? We are also seeing this issue and cannot downgrade our project so are waiting for a resolution.

    Do we have an ETA for this fix? This is holding me from upgrading to 2019.1

    I’m seeing this on Unity 2019.1.4 with Oculus implementation 1.36 and 1.37.

    In my case the jitter problem is on the OVRPlayerController: as I move around, it often looks like it’s skipping frames and the motion is not fluid, even with a basically empty scene.

    2019.1.5f1 - Definitely still present for Oculus Go. Nothing I do seems to help. Moving past a wall with a grid, you can see the vertical lines "doubling up".

    Using the OVRPlayerController prefab.
