[Resolved]Ar foundation camera bg flickers green.

I am getting a weird green flicker all over the camera bg texture, the foreground 3d model remains unaffected. Also what I noticed that when the camera is fully covering the 3d object the flicker intensifies. Whereas when the object is too small it stops flickering. There is something that is triggered when it comes closer in the vicinity of the 3d object.

And this only happens on Android, works fine on iOS. Please refer to this video: https://youtu.be/vJ4s0S4OJkM

Any help is appreciated, thanks :)

Edit 1: It seems to be the fire particles , if i switch off the fireparticles[particle system + point light] the flickering stops. But this behaviour is only happening on android that too only for pixel phones. On other android phones it works fine , and also work fine on ios devices.

Edit 2: It is resolved in the 4.x version of ar foundation. If you can't update to 4.x then disable multithread rendering and the experimental graphics job
