Bug unity 2020 has weird glitch like a z fighting on UI in android

Only happen in android, and only when there is so many ui object in the scene, there would be this weird glitch come out in a frame has movement. But it never happen in 2018 build or even 2020 in desktop editor

The left one is normal visually, the right one is when I have dragging a scrollrect around



What happen and are there any possible fix?

 

In this case you perhaps found a regression. Please submit a bug-report as described in this document:
https://unity3d.com/unity/qa/bug-reporting

It's important that you report these issues together with a reproduction project if you want them to get fixed. If you don't do it, it might be a long time until someone else reports them or until Unity Technologies find them.

After you submitted the bug-report, you receive a confirmation email with a bug-report Case number. Please post the Case number (number only, not the link) in this forum thread for Unity staff to pick up.

 

@Peter77 Sorry I have many complication to use that formal reporting so I can't

But for adding information. This problem was not occur in 2020.2.0a13

 

@LeonhardP I suspect that it was the same issue as

https://issuetracker.unity3d.com/is...41.988810028.1596428200-1008742388.1531366984

Why this doesn't backported to any previous version?

 

@LeonhardP What does it means for `Fix In Review` ?

If it means fix but not released then which version it will? Unity 2020.1.2 just released, is it already fixed?

 

@LeonhardP Currently it said fix for all

But which version is fixed in 2020.1 ?
Is it already fixed in 2020.1.3 or the next release? Or it is fixed from package?

 

@LeonhardP @karl_jones What is the actual state of this bug? I want to revert back to beta version because I want to use cloud build. This is blocking issue for me currently

 

Thank you very much
