unity 2019. when you rotate a pixel art sprite its edges become jagged

Hello everyone!
The attached image clearly shows the problem - the edges of the sprite are "notched"when turning. How do I fix this? Help, anti-aliasing doesn't help. Is there any way to remove these "notches"?

 

Are you using pixel perfect camera? That's likely the culprit here if so.

 

Yes, I do. So it affects the "notches"? can this be fixed?

 

what, it's just unrealistic to solve this?

 

that effect is the point of the pixel perfect camera, you can disable the pixel perfect camera to remove the effect

 

but then the sprites start to shake, sub-pixels appear(

 

check this video at 2:05

thats how something rotating in pixel perfect is supposed to look like

if yours doesnt look like that then maybe its another problem
