    Any thoughts?

    My guess is a beginning to fail LCD panel. I really hope not.

    What I Have Tried

    • Rebooting (no change)
      Changing Users (no change)
      Changing Resolution (no change)
      Taking a screenshot to see if it is GPU or LCD (definitely LCD)
      Plugging in an external monitor (issue is not present on external monitor)
      Ran Apple Hardware Test 3 times no issues

    Guesses? Suggestions?

    Thanks!

    I'm guessing these are smudges inside the LCD.

    I thought about that, but I have never taken the front glass off. How would it get smudges inside?


    Thanks

    The issue seems to have resolved itself. Not sure why.
