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.]

    I've got the same issue on my Surface Pro X.  I simply cannot adjust the brightness.  Currently I have:

    Edition Windows 10 Home

    Version 20H2

    Installed on ‎8/‎16/‎2020

    OS build 19042.746

    Serial number 058897501753

    Experience Windows Feature Experience Pack 120.2212.551.0

    Best I can tell it started after I received this update:  

    January 12, 2021—KB4598242 (OS Builds 19041.746 and 19042.746)

    This is a bit frustrating as I normally use this when I'm sitting outside and now I can't read the screen unless I am indoors.

    I bought this laptop because my Surface Book has been with Microsoft for over 6 months for a warranty repair and I needed something to work from.  It's frustrating because I still don't have the Surface Book, and now I'm having issues with this machine.

    Same here. Surface ProX, screen brightness stuck. Nothing will change it. I went into a store and they fiddled with it something like function or alt or something and it was fixed! ....Until now. Happened again, totally randomly too
