1645571 - Onscreen keyboard dismissing itself, Win10 tablet mode, taskbar auto-hide

Status: NEW

(Core :: Widget: Win32, defect, P2)

Description

[Alexander Vanderveen]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:77.0) Gecko/20100101 Firefox/77.0

Steps to reproduce:

Windows 10 running in tablet mode, with the taskbar 'auto-hide' setting enabled.
'Tap' any text entry field including but not limited to the address bar.

The same is the case for Firefox Nightly 79.0a1 (2020-06-12) (64-bit).

I am running a Lenovo L390 Yoga (2-in-1 laptop with wacom layer, and touchscreen) with up-to date Windows 10 build 2004, all Lenovo software/firmware up to date.

Actual results:

The onscreen keyboard appears, and then automatically dismisses itself as soon as the animation to appear is finished. You cannot make the keyboard reappear until you 'tap' out of the text field, and then back in it again, when the onscreen keyboard once again exhibits the same behavior continuously and consistently.

Expected results:

The onscreen keyboard appears, and persists, until it is manually dismissed, the way it behaves in the new chromium based Microsoft Edge under the same circumstances.

I have exactly the same problem on two different 2in1 Windows 10 devices. When operating in tablet mode with the task bar auto hide feature turned on the onscreen keyboards appears momentarily and then goes away as the task bar hides itself.

The on screen keyboard works properly in Chrome and the new Edge browsers with the task bar auto hide feature turned on.

This only started happening after update to Windows 10 2004. Looks like tablet mode had some changes introduced: https://docs.microsoft.com/en-us/windows-insider/at-work-pro/wip-4-biz-whats-new#new-tablet-experience-for-2-in-1-convertible-pcs-build-18970

I have a Surface Pro 6 with OS build 18363.959 that works fine in tablet mode. Also a Surface Go 2 that used to work fine, but after update to 2004 (OS build 19041.388) now exhibits the described behavior in Firefox - as soon as the on-screen keyboard finishes sliding up into position, Firefox resizes, and the OSK disappears. As the OSK slides back down, Firefox appears to only fill half the screen and I can briefly see the desktop in the background. As soon as the OSK finishes the slide animation, Firefox resizes back to fill the screen.

ui.osk.debug.keyboardDisplayReason is the same for windows 1909 and 2004 - IITM: GetInTabletMode=true.

Hello, I realized this before update 2004. Found several reports of this with earlier versions of firefox. For me, the problem appeared with the new firefox version which was completly redisigned as it says.
Hardware: Surface Pro 5 and Acer mini tablet

Hope it will be solved soon.

Hi
I reconize the same Problem after upgrading from Win 10 1909 to 2004. Upgrading to 20H2 did not solve it. Microsoft support did not know about.
