Question Weird Rendering Cinemachine 2D

First off, I'm extremely new to unity-- talking maybe 6 hours total spent in it so far. What I've learned so far is that, for whatever reason, when I move around the camera renders the map and me very weirdly. Pixels resizing, stuttering, and I have no idea what could cause this and google didn't help.

I would appreciate so much if someone could tell me what is wrong, here is an example

i have the pixel perfect component on the cinemachine camera btw so idk why that's the only thing that would show on google to do

no matter how many tutorials I follow it just stays the same, I've edited every single setting of cinemachine brain but it always awkwardly renders, i have pixelperfect extension on my cinemachine camera but not my main one, just nothing works is there anything i'm missing?
