The Windows11 taskbar does not hide completely, leaving a thin line visible at the bottom.
Hello, after enabling the taskbar auto-hide feature, a thin line remains visible at the bottom and won't fully hide. This issue appeared suddenly without any specific action triggering it. Please advise on a solution.

I'm regularly having this same problem (gap below the taskbar that reveals wallpaper image). I have Scaling and Resolution set to the recommended values (150% / 3840x2160) and the Taskbar is set to not hide automatically. I'm running Windows 11 Enterprise 25H2 build 26200.7705, Experience Pack 1000.26100.291.0.
The issue is easily (albeit temporarily) corrected by restarting explorer.exe but returns at some point during the day, presumably from plugging/unplugging from external monitor, resuming from sleep, or some other trigger.
The thin line remaining visible at the bottom of your screen after enabling the taskbar auto-hide feature is a common issue in Windows. It often happens due to display scaling, graphics driver glitches, or taskbar settings.
Ensure your display resolution matches the recommended setting. Mismatched resolution can cause rendering artifacts.
Right-click on the taskbar and select Taskbar settings.
Turn off Automatically hide the taskbar in desktop mode.
Wait a few seconds, then turn it back on.
Check if the line disappears.
Right-click on the desktop and select Display settings. Under Scale and layout, try setting the scaling to 100% or a recommended value. Log out and log back in to see if the line disappears.
