Windows Terminal version

1.19.3172.0

Windows build number

10.0.22621.2861

Other Software

WSL

Steps to reproduce

Unknown. Sometimes reproduses after wakeup, sometimes if secondary display is connected/disconnected, sometimes no noticeable trigger.

Expected Behavior

  1. Maximized window does not overlaps autohiding taskbar
  2. Maximized window does not initiates do-not-disturb mode

Actual Behavior

  1. Minimized taskbar is overlapped by Terminal window and does not show up with mouse cursor.
  2. Windows enables do-not-disturb mode as for full-screen gaming app.

Screenshot to show DND mode, taskbar here is shown by pressing Win key:

@zadjii-msft commented on GitHub (Jan 3, 2024):

Hmm. Having more consistent repro steps would definitely help investigate this. I know that the auto-hide taskbar is really peculiar in the way it behaves with secondary displays. Perhaps if the terminal started maximized on the secondary display, then that was disconnected, and the Terminal restored on the main display, it might to cover the taskbar on the primary/?

But I think we'll need something more concrete here to be able to look into this further 😕

100% reproducable:

  • setup:
    • Windows 11 Home 22H2 22621.3007
    • 2 displays:
    • main, scale 100%, taskbar enabled with autohiding
    • secondary, scale 200%, no taskbar
    • auto-enabling do-not-disturb mode enabled for notifications is turned on for:
      • gaming
      • full-screen apps
  • steps:
    • minimize all windows (via Win+D or Win+Comma+click)
    • switch to terminal window (via taskbar or Alt+Tab)
  • steps to restore expected behaviour: toggle back and forth terminal's window maximizing in window header top right icons

0% reproducable:

  • setup:
    • Windows 11 Pro 23H2 22263.3007
    • 1 display (laptop internal), 200% scale factor
  • steps: the same

I'll add steps the unrestorable state (no way to have terminal maximized with taskbar autoshowing with mouse pointer, except reboot or mb restart shell) repro if encountered again

may be it is more related to "game" and not to maximizing/autohiding/secondary display, because autohidden taskbar's 1
-pixel line is hidden in full-screen games (as it should)

sometimes maximized terminal falls into that mode for unknown trigger, sometimes when display turned off/on due to powersaving timeouts

It seems like the behaviour is not Terminal-specific: just got the same with Brave browser maximized on sidescreen (display restarts sometimes due static electricity discharges nearby).
But some apps does never behave like this, e.g. PhpStorm.

Hmm

            // Prevent Windows from going into do-not-disturb mode when this window is fullscreen.
            ::SetProp(window, L"NonRudeHWND", reinterpret_cast<HANDLE>(TRUE));

https://learn.microsoft.com/en-us/windows/win32/api/shobjidl_core/nf-shobjidl_core-itaskbarlist2-markfullscreenwindow

Setting the value of fFullscreen to TRUE, the Shell treats this window as a full-screen window, and the taskbar is moved to the bottom of the z-order when this window is active. Setting the value of fFullscreen to FALSE removes the full-screen marking, but does not cause the Shell to treat the window as though it were definitely not full-screen. With a FALSE fFullscreen value, the Shell depends on its automatic detection facility to specify how the window should be treated, possibly still flagging the window as full-screen.

Since Windows 7, call SetProp(hwnd, L”NonRudeHWND”, reinterpret_cast(TRUE)) before showing a window to indicate to the Shell that the window should not be treated as full-screen. This ensures the taskbar does not adjust itself to be below the window in z-order. This is similar to ITaskbarList2::MarkFullscreenWindow(FALSE) except the Shell will not fallback to its automatic detection facility and will not treat the window as full-screen.
