Pixel Perfect Camera Jitter

Hello, I'm currently working on a 2D pixel art game for w$$anonymous$$ch I use the pixel-perfect camera. I have the upscale render texture option turned on, though with the camera following the player objects such as the sword or the mouse sprite jitter to an extreme extent. I've encountered t$$anonymous$$s problem before, and have never been able to solve it, so any help with t$$anonymous$$s would be greatly appreciated.

Here's a link showing off the problem: https://youtu.be/9TqEHo9fSTM
