Hi there

Edit: Its more clear in this. Images melt down after fade in/out. - YouTube

As you can see in the video, some meshes flicker a lot in vive and vive pro. Its more noticable in the headset. This started to happen around 2 weeks ago(at least thats when I noticed it)

1- This doesnt happen in spectator camera

2- This doesnt happen with every mesh

3- This started to happen in a packaged project like from 2 years ago. It wasnt happening before. On 4.17

4- This doesnt happen in a clean VR template

5- It happens mostly when I move my head. And happens constantly

6- It happens on my project right now. On 4.19

Weirdest thing is that, packaged project was all fine. Because of this, I think either Nvidia or Steam or Windows messed up somewhere between that time period.

Any ideas how to fix it?

Have you tried on 4.21? I just started working on a VR project with the Vive in 4.21 and haven’t had any issues like that. It almost looks like some z-fighting at the edges there, is that cross walk a texture on the ground or a separate actor?

They are separate actors but its not a z-fighting. Like I said, this started to happen in my old packaged project. I looked at that and showed that to my customers countless times. This wasnt happening before. This happens all over the place. Its espcially terrible when I fade in/out for teleporting. Its like my screen is melting in front of me.

Gonna try 4.21 now

Enable Motion Smoothing was causing this one - YouTube. I didnt have time to test other one.
