AE rasterise vector layers

Hi everyone!

I decided to scale ai objects in AE, and have noticed the low quality of files.

Thought it was because objects have been manipulated, but imported a fresh one in new comp and have the same result.

Tried to fix with by changing the dimensions in AI; changing the thickness of the line in AI; ticking the box for "continuous rasterize" and precomposing with and w/our rasterization. The weirdest thing is that the Shape layer has the same quality as imported files while the resolution is full.

Could you give me a tip, please, what it could be?

Thanks!
