Print noise?

Has anyone experienced this type of "noise" on printings? Is looks like its only happening with cylindrical models, no matter what model i make. I checked them with Meshmixer for errors, etc and still get this weird kind of "pixels" printed on surface that are not part of the model.

Please help!

I appears that it could have something to do with the Model Supports feature incorrectly calculating supports on cylinders.

What slicer are you using. Do you have supports enabled

i?m using Simplified3D

In this placece print speed is change a little bit . please check it.
