    I use Sequences.
    The environment is as follows.

    Unity 2022.2.0f1
    Sequences 2.0.1

    When checked in the Profiler, the Self ms in
    UnityEditor.Sequences.SequenceIndexer.RecomputeSequencesValidity
    is a very long time because the operation is very heavy, except during timeline playback on the Editor.

    This does not occur in the following environments.
    Unity 2021.3.12f1
    Sequences 1.1.0

    Thank you in advance for your help with the above.

    Having any playable director on the scene now improves performance.
    This is so strange.

    During the update, the following error was missed.
    We do not know what this error means, but it seems to be related to this bug.

    "Library\PackageCache\com.unity.sequences@2.1.0-pre.1\Editor\Core\Utilities\IconUtility.cs"

    If you comment out as follows and restart UnityEditor, the behavior seems to be improved.

    Code (CSharp):
    1.         [InitializeOnLoadMethod]
    2.         [ExcludeFromCoverage]
    3.         static void PreloadIconsOnStart()
    4.         {
    5.             //EditorApplication.delayCall += PreloadIconsWithDelay;
    6.         }

    Hi there! Thanks for the feedback. We weren't aware of this issue and have now logged it on our end so we'll take a look.

    As a side note, it is normal that this issue wouldn't occur in Sequences 1.1.0. The 
    RecomputeSequencesValidity
    mechanism was only added in 2.0.1 when we moved from IMGUI to UIToolkit.

    I've updated to the latest Unity and the latest Sequences, but it still doesn't seem to be fixed.
    What is the status of this matter?
