Then, my question would be, how the taskbar go to hidden mode while you have chosen just to hide if you have Windows maximized or something Infront of your taskbar. This show, perhaps there is conflict somewhere. Hence my suggestion, to try the clean boot step to help iron out and identify any application that is causing the conflict.

Thank you,

I turned that off because that was not the issue, how can  do a clean boot, it could take hours before the  line shows up again, i have many apps, am supposed to take weeks to go through every app and hope that is the problem?, lets be realistic, what   I am going to do is turn off start 11 handling taskbar, if issue does not pop up in about a day  i know it is start 11

Thanks Haalee - very good summary of the observed problem and findings to date. My gut feeling - definitely a screen redraw/rendering issue and not a driver issue. Somehow the Start11 taskbar is leaving a black line on the monitor that corresponds (often, but not 100%) to the top of the taskbar itself.

Not a crippling issue, as an explorer refresh or activity on the monitor makes the line go away. More of an irritant.

No black line since disabling start 11 taskbar but now windows still think i am using start 11 taskbar and it keeps disabling auto hide

Is your taskbar at the bottom of the screen?

Thats the only supported configuration for autohide in Windows 11 without the Start11 enhanced taskbar.

Yes

I have completely disabled the Start 11 taskbar yet  windows keeps telling me i can't autohide because another program is autohiding the taskbar

Have you tried turn this setting off?

Thank you,

Yes that is what I did

Just to be sure, turn that back on and turn on enhance taskbar, and go into Start11 enhance taskbar setting and make sure the Autohide is disabled while in there. once that is off, check on Windows taskbar setting->Taskbar behaviors-> try turning on "Automatically hide the taskbar". Does that work?

Thank you,

Hello,
Sorry to hear you are having issues. That screenshot talking about hidden "toolbar" not really sure if that the same as Hidden taskbar. And from what I know, toolbar is something from Windows 10 and no longer available in native Windows 11. Perhaps, you're using other 3rd party application to bring it back?

Thank you.
