Harald написалUnfortunately we could not reproduce this problem. Does the problem not occur when you disable the New Render Objects
render feature?
Could you please send us a minimal Unity project that still shows this problem, as a zip package to contact@esotericsoftware.com. Then we can have a look at what's going wrong.
After few trying to solve the problem, i have assurance my problem is related with some kind of unity's bug.
I just move z position of main camera and restart project. And then, all problem gone.
I can't believe this. Because ScreenSpace-Overlay is not related with camera's position.
It seems that unity has some kind of bugs only occured on first setting of URP.....
Anyway, problem does not occured with same project now.
But for other users who can suffer same problem, i will create and send other project can reproduce problem in today.
