    Hi, in my game when I move my character, the UI layer jitters rapidly left and right by a single pixel.
    I thought and checked if it had anything to do with cinemachine or moving with FixedUpdate but the issue persisted when both were unused.

    Here are my settings for the canvas and the camera: upload_2023-2-14_0-39-2.png

    Have you tried just making the Canvas render mode be screen space overlay instead of screen space camera?

    What you're seeing might be some weird interaction of the cinemachine brain with the pixel perfect stuff. If the UI canvas is already low-res and static, no sense in re-pixel-perfecting it.

    Setting it to overlay solves the jitter, but it fits itself to the game viewport size, and not the cropped frame size.
    Also, it doesn't receive my post process effects.

    Please use the dedicated UI forums when discussing UI.

    I'll move your post to the correct forum.
