1919163 - Jumpy awkward Firefox window, tabs and content when the Windows 11 Touch Keyboard is active in tablet mode.

Status: UNCONFIRMED

(Core :: Graphics, defect)

Description

[w1ldr3dx]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:130.0) Gecko/20100101 Firefox/130.0

Steps to reproduce:

Device Info:
Microsoft Surface Pro 11 Tablet with Qualcomm Elite X (ARM64)

Steps to reproduce:

1. Install Firefox on a Windows 11 Tablet
2. Make sure no keyboard is attached and no bluetooth keyboard is connected.
3. Open Firefox
4. Touch into the Firefox address bar to make the Windows Touch Keyboard becomes active.
5. Then touch elsewhere and touch back to the address bar.
6. Watch the Firefox title/tab bar and window content.

Actual results:

The Firefox title/tab-bar moves and changes the height, the tabs snaps more to the top and a bit to the right as if it's jumping, they move back when you touch elsewhere.
The Firefox window content (e.g from a site) becomes clone ghosted and slides awkwardly away.

Expected results:

The Firefox window, the tab-bar, tabs and the content should stay where they are when the Windows 11 Touch Keyboard becomes active and the users touches into the address bar.
Btw.:
The same happens on Thunderbird, it must be a piece of code that affects Firefox and Thunderbird.
This does not happen on Chromium browsers, so it's not a Windows 11 bug.

From the above screenshot, it appears that this isn't isolated to the address bar as a number of elements shift when the on-screen keyboard begins displaying. It wasn't immediately clear which component this might be related to, so feel free to move to the most appropriate one.
