Screen Flickers AR Android URP

[apiotuch_unity]

Hello,

I had AR using ARFoundation going with standard pipeline. I converted my project to URP. Now when I move the Android device around to scan the room, the screen flickers grey. Sometimes full screen, other times it is blocks of grey. It looks like some sort of rendering interruption. I have not tested with iOS. This flickering only occurs when the AR camera is on.

Update:

I believe it occurs when a raycast no longer detects a ground plane or when it first detects a ground plane.

Have you solved this already? I’m trying to fix it too.

Not yet. I did manage to cut down some of it. Any of my objects that I instantiated I made them children of an AR Anchor. That cut down half off the flickering but I still get flickering when I look away from the ground plane.

I had this same issue. I went into my build settings → Other Settings and unchecked Multithreaded Rendering and it went away.

I had this same issue. I went into my build settings → Other Settings and unchecked Multithreaded Rendering and it went away.

Disabling Multithreaded Rendering actually made it always gray.

Update:
I tried it again with it disabled. Looks like the permissions popup was interrupting something causing the constant gray screen the first time. When I entered it again it was fine. No flickering.

Note our FAQ :

Is a forum post the same thing as a bug report?
No. The forums can be a great way to seek advice from the development community, but Unity does not track bugs that are reported in the forums. To file a bug report for the Unity Editor or any Unity-published packages, use the in-Editor bug reporting tool: Unity QA: Building quality with passion.
