Help needed with a super odd rendering flicker issue

Unity Engine

After upgrading from Unity 2021 to Unity 2022.3.38, some of my Android players started seeing this odd rendering flicker glitch in very few UI components.

1 Text Mesh Pro component and 2 Canvas Image components.

But essentially it’s the top yellow text, bottom center silver box, bottom right back arrow.

I tried breaking down the UI to more canvases, disabled Pixel perfect canvas, disabled multi-threaded rendering, and I just can’t find the cause.

Any help will be greatly appreciated.

Thank you.

no ideas, but lots of 2d updates between those versions,
https://alpha.release-notes.ds.unity3d.com/search?fromVersion=2021.3.42f1&toVersion=2022.3.38f1

if nothing else comes up,
could try different versions between those 2021 > 2022, to pinpoint where it exactly happened.
(or just report as bug, sometimes they answer pretty quick)

Seems like I have solved it. By the looks of it, seems to be related to this

Might have been that these objects shaders, and TMP font shader was used in world objects, and for some reason starting from Unity 2022, for this particular project, it started causing these issues. It’s hard for me to confirm 100% that this is the problem because I made a bunch of changes and I couldn’t replicate the issue myself.

Thanks for the help!
