Hi Nikita, for the edit frame scaling center it will switch between "scale from center" to "scale from opposite corner" every time you click (press and release) on an edit frame handle instead of dragging on it.

It's just a display artifact from the realtime viewport display being oriented towards speed. When you export you'll be using the export mesher instead of the viewport display mesher and you can generate a denser mesh at that time.

So that's not anything wrong with your model, it's just something to just ignore.

What happens is that curves are drawn to a high degree of accuracy by dynamically refining them to appear smooth at the current view zoom level. It's unfortunately too expensive to do the same thing with surfaces so shaded surfaces get just one display mesh generated for them and when you see gaps like that it just means the surface display mesh did not get a lot of triangles made in those spots.
