    f I switch the virtual camera from A to B and quickly switch to A before switching to B, it will cause the blend to become very fast and inconsistent with the configured blend time

    Does the problem happen in a build, or only in the editor?

    This problem exists both on the PC and in the editor.

    I don't quite understand your answer. I tried to reproduce the issue that you showed in the video, using the Cinemachine sample assets. I was able to repro the stutter when I played the scene in the editor, but when I made a build of the scene and tried that, it was perfectly smooth. Did you try that?

    Can you tell me why smooth in a build? I try it in my project and get a smooth result too.

    Because the Unity editor has lots of overhead that can generate uneven frame rates. Cinemachine damping is sensitive to uneven frame rates, and you might see jitter when that happens. It's not impossible to see it in a build, but it's less likely.
