App Flickering on iPhone

September 23, 2021 - 3:29pm #1

Hi Everyone,

 

I am trying to develop my first App and am using Vuforia with a model target.

I have a script that uses raycast to detect objects.

For a bloom effect that I want to achieve I added the URP (Universal Render Pipeline) addin.

When I test the App directly in Unity on my Macbook everything looks just perfect.

However when I write the App to my IPhone via XCode, the result has some error.

The screen starts flickering in all kind of colors from red, blue, green, yellow.

What I noticed is that if I direct the camera to a "quite" aim like a wall it stops flickering, if i direct it to an area where a lot is going on like in the screenshot it starts flickering heavier, almost like you can see it calculating...

So when I switch off the PostProduction in the (Vuforia)Camera the bug does not appear.

 

Please have a look at the screenshot attached.

 

I would be happy for any hint, how to fix this.

I also googled a lot for this bug but didn`t find anything comparable.

 

Thx, Jonathan

Also would be great if you can share your Unity, Vuforia Engine, and URP versions!

Hey there,

 

Is there any possibility you can simplify and share your zipped project? I assume that the post processing is trying use the camera frames that are used by Engine and therefor you are seeing these artifacts.
