How to make an object move smoothly in Canvas so that the object doesn't flicker when it moves?

Question

JavaScript

Hello, I made the object move smoothly with requestAnimationFrame, the object itself flickers along the way, it is blurry, as if twitching back and forth.
Here's an example: demo
Look at the circle's frame, it's blurry as you move. Especially the top left corner and the bottom right corner.
I didn't do anything magical, just x += 8 and y +=8. Tried to use Three.js, Pixi.js there is the same story.
What I don't know yet, what's the catch? :)
Update 1: Simplified code, demo

Answer 1

If you reduce the speed - the effect is noticeable? There is just a suspicion of the reaction speed of the monitor.

Answer 2

The question is not described where the tags are. Where is the code. Asla la vista!
