Surface Pro X display brightness issue.

I'm having an odd experience with the screen brightness of my SPX. Here's the sequence:

  1. Turn on the SPX to wake it from sleep. The screen appears to be at about 60% brightness.
  2. Press F7 (increase brightness). The screen brightness widget appears briefly, showing 100% brightness. The screen brightness doesn't change.
  3. Open Settings, navigate to System ->Display page. The Display brightness slider is at 100%. (Change brightness automatically is unchecked.)
  4. Click the Display brightness slider at about the 80% mark. The screen immediately brightens (confirming that it was well below 100%).
  5. Click the slider at the 100% mark. The screen brightens to 100%.

This sequence is the only way I can get 100% brightness after the SPX has been in sleep mode. Thoughts?

[Note: this is with the SPX connected to power. I haven't tried it on battery. The advanced power settings are standard Balanced. The system is on Windows Insider Fast Track, and is up-to-date.]

    Nope. Still waiting. (Even if it is a hardware issue, we know that it could be fixed with a simple bit of software added to the wake-up sequence.)

    You know how the screen turns dim right before it turns off?

    I think it never turns bright again after you wake it up again. I tested my theory a little and it seems to be correct.

    Just go to settings -> System -> Power & Sleep and change turn screen off to never or something really high. Battery life on the pro x is amazing anyways.

    Cautiously, with fingers crossed, I can report that the latest Insider Fast build (19613) seemsto have fixed at least one of the Surface Pro X screen-dimming issues - the "screen is dimmed on waking even though Settings shows 100% brightness" bug.
