Sampler error or bug?

This error does not occur in the blender, but in the sampler.
This error changes the texture.
Pictures 1 and 2 are from the blender.
Picture number 3 is the one you can see in the sampler.
It's not a blender error, it's a sampler error.
Small holes as well as wireframe errors often occur in samplers. Is it because it's the beta version?
Does Adobe know this problem?
