Wierd artifacts on edges when using pixel perfect component

Hello, I’ve been using pixel perfect component from urp. I wanted to make UI scalable, so I enabled cropping. I noticed artifacts of repeating frames on the black edges as seen on the image. These apear whenever I move any UI element over them. How do I fix it? Am I doing something wrong or is it a bug? Thanks for any help.
