    Just saw this further down the thread and ran the Terminal command. Mine is showing:

    Extension ID: com.adobe.illustrator.OnBoarding
    Illustrator: 30.8.2
    macOS: Tahoe 26.6.2

    All of the CEPHtmlEngine processes in the output are pointing to that same Illustrator OnBoarding extension.

    Yep, STILL HAPPENING. I’m using a 14 inch 2023 MacBook Pro running macOS Tahoe 26.6.2. I usually have Photoshop, Illustrator and XD open. The Studio Display will not automatically turn off or enter display sleep according to the macOS Lock Screen settings.

    I confirmed that the macOS display sleep setting itself is working correctly. I temporarily set "Turn display off on power adapter when inactive" to 1 minute, but the display remained on indefinitely.

    Activity Monitor did not initially identify an obvious application as preventing sleep.

    I then ran pmset -g assertions in Terminal.

    While the problem was occurring, macOS reported:

    Assertion status system wide:
    PreventUserIdleDisplaySleep 1
    PreventUserIdleSystemSleep 1

    The relevant owning process was:

    CEPHtmlEngine

    with the assertion:

    NoDisplaySleepAssertion named: "Video Wake Lock"

    CEPHtmlEngine had maintained this assertion for approximately 74 hours.

    CEPHtmlEngine:
    74:33:59 NoDisplaySleepAssertion
    "Video Wake Lock"

    I completely quit the Adobe applications and ran pmset -g assertions again.

    Immediately afterward:

    PreventUserIdleDisplaySleep 0

    The CEPHtmlEngine "Video Wake Lock" assertion was completely gone. The only temporary display assertion remaining was the normal macOS power management delay:

    InternalPreventDisplaySleep
    "com.apple.powermanagement.delayDisplayOff"

    That assertion had a short timeout and released normally.

    After quitting the Adobe applications and clearing the CEPHtmlEngine assertion, the Studio Display successfully went to sleep after the configured 1 minute period.

    CEPHtmlEngine should release its NoDisplaySleepAssertion when there is no content requiring the display to remain awake, instead it maintains a persistent "Video Wake Lock" for an extended period, preventing macOS from putting the display to sleep even though no video or other content requiring the display to remain awake is playing. Quitting the Adobe applications removes the assertion immediately and restores normal display sleep. This appears reproducible and directly associated with CEPHtmlEngine rather than the macOS display sleep configuration.
