Question player controller shakes when jumping forward in a certain object

so i have made a player controller with controller.Move(move * speed * Time.deltaTime); and when i jump while holding W in front of a wall i somehow shake up and down. i recorded a video so you can understand.
i have no idea what causes it

 

I have same problem, may be you didn't notice but it also happens if go backwards or sides and try to jump.

 

I found solution! Maybe it's not that smart, but it works. Reply to me if you need an answer.
