URP Lit Shader Showing White Dots After Upgrading to Unity 2022.3.34f1

Problem

After upgrading my project from Unity 2022.3.16f1 to 2022.3.34f1, some materials using the URP Lit Shader are showing white pixel artifacts (speckle/dots), both in-scene and in the material preview itself. These white dots do not appear in the build.
During upgrade it also updated, among other packages, URP version from 14.09 to 14.0.12

Also tested versions 2022.3.47f1 and 2022.3.64f1, same artifacts.

These appear consistently under certain lighting/material combinations.

Reproduction Conditions

  • Unity 2022.3.63f1
  • URP version: 14.0.12
  • Shader: Universal Render Pipeline/Lit
  • Platform: Android Editor
  • Renderer: Forward and Deferred (both tested)

Observations

  • Dots appear in the material preview (it happens in preview sphere) even without any scene lighting.
  • No normal map, no mask map.
  • Disabling Receive Shadows or Specular highlights removes the dots.
  • Enabling Alpha Clipping also removes the dots.

What I’ve Tried

  • Reduced lighting intensity and removed post-processing.
  • Adjusted shadow bias and light settings.
  • Switched from Skybox to flat ambient color.

Expected

URP Lit materials with valid PBR values should not show visual artifacts like NaNs or white dots, especially in preview.

Request

Is this a known issue with URP in Unity 2022.3.x?
Are there updates, workarounds, or shader fixes I should apply?

For the moment I’ll just switch back to a previous version of Unity where these artifacts don’t happen (2022.3.16f1).
I asked a colleague to try to open the editor in his computer (i have an HP with no dedicated graphics card and he has an MSI) and it works just fine for him, no artifact whatsoever

I fixed it by switching build type from android to pc

Yeah i remember i tested switching from android to PC and it worked but in my case i needed to work in android platform. Later i upgraded to another laptop and i got no issues since then
