Oculus Quest Vulkan rendering artifact
Hello,
After switched to vulkan we saw a huge performance improvement over es3.1, but the weird rendering artifact appears.
As shown in the above image, there are purple dots shown on screen and we don't know what's causing it. Also, when building our game in development mode with vulkan enabled, the game will crash at launch. We are using the latest Unreal 4.22.3 pulled from oculus' repo(commit 73f652a56eeb7311db5377b9c4addeb8d16142cb). Please help.

- Did you figure out this glitch? I've also had purple squares and they're sometimes there and sometimes not there. It's on a mesh that has a number of materials. Same build as you.

Not yet, I'm not a rendering expert :'( . Just want to raise engine dev's awareness to this issue, hope for a fix asap. - I think it might be related to transparent or masked textures. I've seen it in multiple projects and had to revert to es3
