5.4.X visual glitch after enabling meta xr

[BrotherOfPureEvil]

Hi guys, i am trying to fix this for 2 weeks now. I have a glitch, it apear on every project after enabling meta xr plugin. 

it happen to show on XR API - Oculus OVRPlugin + OpenXR backend (without this i have not glitch but also i dont have passthrough, and i need it)

also glitch happen to repair after checking mobile HDR but then i also lost passthrough but also proper colors.

in every other cases i checked with diffrent settings, glitch persists. do you know any viable settings or whatever?

I dont have any lights on map, i deleted all of them in search for fix.

Hey Brother,

Glanced at your video and the pattern is very similar to the Fixed Foveated Rendering cone.

The technique uses chunks of the screen to scale down. What you're looking at is likely some conflict in this process. First step I would try is check plugin and check Rendering settings both and make sure the FFR is off. Might be worth a try.

I have seen deprecation in this pipeline multiple times in UE5 as the plugin iterates and the artifacts tend to look very similar to this. Good luck!

Hey,

I have the similar problem. UE5.4.4
Tried the metaXr plugins V67, 68, 69, 71, but got the same graphical glitch.
Downloaded from github the MetaXr Passthrough sample project, that show this graphic problem too.
Played the FFR, not helped... 😞

UPDATE:

Tested on other Quest 3 with V69 system, the problem not showed up.
I have V71 os on my quest.

What now?

what diffrent google no problem? mine has v69 and problem occurs

[Biggs]

He all- want to double check and make sure you have turned off Fixed Foveated Rendering in both the rendering settings and plugin. Again, not positive it is the issue but it looks extremely similar to other rendering/shader complexities I've ran into in my own work. I've had to keep this off on a recent project due to similar artifact patterns.

Plugin and Rendering sections of Project Settings:

Hi, both setting is off/disabled, as on your attached pictures.
This problem since i updated the quest 3 from V69 to V71.

[BrotherOfPureEvil]

yeah i already stated that i checked different settings, and foveated was first of them and nothing helps. I just manage to fix flickering but not rectangles.

in my googles i manage to fix it by compiling meta fork unreal engine, but this version has many compatibility issues with plugins

Hello!

I reinstalled Unreal engine, the android SDK and the Java, based on this tutorial, now works fine, the graphic error not shows up. (V71 MetaXR plugin)
