Issue with rotating image

Hey, i got problem with my Unity Project. I want to rotate image in z axis (slow, something like 20 deg per second). The problem is when i rotate this image, it starts deforming (like scale is slightly increasing and decreasing very fast). I read that it might be because of parent’s scale but it’s still (1, 1, 1) so idk.

Ok, i found the problem. I had to disable Pixel Perfect in Canvas. Closing subject.
