Random Square Pixel appearing

[daniel Mora]

Hello,

I am currently using a texture on a model but a random square pixel appears on top of the texture with no way to remove it. The square is not on my texture and doesn’t appear in the material editor either but I don’t know how to get rid of it. Is it a UV problem or a problem with the texture itself?

Thanks in advance!

Does it appear in the final render or just in the viewport?

Try changing the texture preview resolution to no scaling or a high value and see what happens:
Material Attributes > Editor > Texture Preview Size
