unity – The right way to stop glitches in script-driven animations?

I’ve animations which are performed through script. Sometimes, glitches happen at runtime that I am unable to clarify. Right here is an instance:

These glitches don’t happen constantly however seem in nearly all animations. They appear to occur solely when one other animation is taking part in concurrently. As proven within the define, the animation itself ought to be right. Right here is the code used to play the animations:

non-public void PlayState(string tag, bool stopAfter = true)
{
    animator.enabled = true;

    if (!HasState(tag))
    {
        Debug.LogWarning($"No state with tag {tag} discovered.");
        return;
    }

    var stateInfo = States(tag).Random();

    if (stateInfo == null)
    {
        Debug.LogError($"No state with tag {tag} present in checklist.");
        return;
    }

    animator.Play(stateInfo.Identify,0,0);
    currentState = stateInfo;

    if (stopAfter)
        StartCoroutine(WaitUntilFinished(stateInfo));
}

non-public IEnumerator WaitUntilFinished(StateInfo data)
{
    var shortNameHash = Animator.StringToHash(data.Identify);

    // Wait till animation is definitely performed.
    yield return new WaitUntil(() => shortNameHash == animator.GetCurrentAnimatorStateInfo(0).shortNameHash);

    var cur = animator.GetCurrentAnimatorStateInfo(0);

    if (cur.loop) yield break;

    yield return new WaitForSeconds(cur.size);

    if(currentState != data) yield break;

    Cease();
}

public void Cease()
{
    spriteRenderer.sprite = defaultSprite;
    animator.enabled = false;
}

I’ve already tried eradicating animations that I suspected had been defective, however this conduct happens with many various ones. Due to this fact, I think the problem lies in my script. How can I stop these glitches?
