Color banding on Bloom effect - PostProcess V2

Hi, I try to get bloom/glow effect on android, it work, but I get color banding (see screenshot).
I try to enable the HDR but the problem still exist.

im working on unity 2019.1.6f1

anybody know how to fix this?

thanks

 

Looks like it could be a source texture format issue. Unity's builtin bloom doesn't specify what sort of source texture it needs, it just assumes what its given will be the correct format of HDR - this means, if for whatever reason the texture fed into it is a very low bit depth format, the bloom's entire chain will use that format throughout the effect, possibly causing banding.

To know for sure though, what Android device/OS/graphics API are you testing it on?
