MouseMove too rare? Or a long drawing?

I noticed that MouseMove doesn't work enough often (visually), as it really is needed. I caught this situation several times in different code and it looks awful and hurts the eyes. Perhaps my perception is distorted, but it seems to me that with a large number of elements on the screen it works even less often.
P.S. Perhaps I do not understand how to handle such situations correctly and I should do something like redrawing on my own. Please tell me if this is so.
So, for example, I have a simple code in my manipulator.

Code (CSharp):

1.  
2. public class TestManipulator : Manipulator
3. {
4.     public VisualElement element;
5.  
6.     protected override void RegisterCallbacksOnTarget()
7.     {
8.         element = new VisualElement
9.         {
10.             style = {width = 4f, height = 4f, backgroundColor = Color.red}
11.         };
12.         target.Add(element);
13.         target.RegisterCallback<MouseMoveEvent>(e =>
14.         {
15.             element.style.positionType = PositionType.Absolute;
16.             element.style.positionLeft = e.localMousePosition.x;
17.             element.style.positionTop = e.localMousePosition.y;
18.         });
19.     }
20. }
21.  

It just shows the red dot exactly under the cursor. However, this is not always the case. Very often comes across something like this:


I easily reproduce this effect even in Unity examples. Pay attention to the yellow circle, the cursor is pressed in the same position. And I move the object quite a bit.



I know that this may not seem critical enough, but my eyes cannot stop seeing this, I just see how the element goes smoothly and then may not keep pace with the cursor and as a result moves unevenly.
When the elements get quite a bit more and they are a little more complicated, then I can find points in which I see such a result every second frame of my gif. In fact, they are much more, just gif is written with a rather low frequency.

In general, this creates the feeling that there is some noticeable delay between MouseMove and drawing.

P.S.
element.MarkDirtyRepaint() does not help solve the situation

 

nope sorry
I can publish them with a bad description and without a project, just giving a link to the forum
