Problem
Upon booting my machine, the lock screen displays a visual glitch where the Windows Hello fingerprint icon is misaligned and a portion of the screen is darkened.

Actual Behavior
* The Windows Hello fingerprint icon is centered on the left side of the screen.
* The left side of the screen is darkened. Sometimes, only a quarter of the screen is darkened instead of the entire left half.
* This issue occurs regardless of which Lock Screen image is configured.
* Visually, it resembles the Windows Snap layout effect (as shown in the attached photos).

Has anyone encountered this specific lock screen layout issue before? Any help or troubleshooting suggestions would be greatly appreciated.

Did you try disabling windows hello, reboot and register hello biometric to see if it resolves the visual glitch?

Question: Does this happen only after a cold boot or does it also happen after a reboot?

Yes many times. It didn't. What did was disconnecting the Kensington VeriMark fingerprint sensor. Changing to a VeriMark 2 (ESS compatible) brought the problem back. Have since correctly implemented Enhanced Sign-On Security and no problem since (so far)

Both. Seemed somehow to be linked to VeriMark fingerprint sensor. Upgraded to VeriMark 2 with ESS set up correctly and so far no problems. Thanks for your interest.

Yeah, I was wondering if Fast Startup might be to blame, but that would have only been an issue if it happened only after a shutdown. Is it possible that the display driver could be at fault? Do you have the latest driver from the manufacturer?

Problem back again! Only once in 20 or 30 starts but still. When this first occurred I suspected the display driver and tried to update it. however the installed driver was the latest. Dell then homed in on the Kensington sensor as being the source of the issue. This now seems unlikely given it is a new model with different software but the only way to rule it out is to disconnect the sensor for a protracted amount of time and see if the problem occurs, which I'm reluctant to do as it took so long to set up!

Could you simply go into Device Manager to temporarily disable that sensor and then re-enable it when done testing?

There is one snag with this approach, with the fingerprint sensor disabled the fingerprint icon doesn't appear at all, but at least there has been no 'darkening' of the left half of the screen since disabling. Will re-enable, but even if the issue returns I have a feeling it will prove difficult to convince Kensington there may be an issue with their driver.
