Need to fix wall contact. Displace the object from wall so little to remove the contact

check too duplicate polish in the mesh

If polygons are okey (no double polygons, and so on), artifacts like one on the last image (black noise on some polygons) can be caused by some Kray bug.
It's easy to check. Change "Backdrop Color" in "Backdrop" tab to any other color. If noise on yours render will change color as well - it's a bug.
It happens when you use Environment plugins instead of environment made by actual geometry - like GI Sphere for example.
Workaround: Use Geo. Sphere for Environment. Noise should be gone after that.

I had very few interiors with such bug, it happens with complex exteriors mostly.

i have 1 scene too with the 1º image problem.
On the begining the render work fine but when i make changes in mesh appears this box transparent on my model.
I fix this separating the object from wall.

Can you show an image or share the scene?

Here is the images. You can show the error when the text is on the wall.
