Bug Some animator states will restart after a couple of frames (creating a visual glitch)

    Hey ! I have a situation where I have 3 states for an attack sequence (windup, action, recovery).
    The states are linked together with 1 transition which has:

    Exit Time = 1
    Transition Duration = 0

    And no other conditions.

    In Play Mode, 99% of the time, the action phase will start playing, then after a couple of frames, will restart from the beginning, causing the animation to "rewind" and creating a visual stutter. Same for the Recovery animation.

    When just stepping (ctrl + alt + p), the issue happens only 1% of the time.

    Here's a gif of it running at normal speed (it's quick, more noticeable on "recovery" in the gif):

    Here is stepping in editor:

    This is also noticeable in build. There is no code calling these states. It's not just a state machine visual bug, I can see the character also going back and glitching in the scene.

    Anybody with the same issue ?
    Any fix or insight would be greatly appreciated :)

    For anyone having this issue:
    I've done a lot of other tests.

    The only thing that fixes it for me is having
    EXIT TIME = 0.9
    (although I'd have preferred not having any transitions)

    Anything with EXIT TIME = 1 can trigger the issue
