Wayland: Cursor is 90° rotated on rotated screen

[Vadym Abramchuck]

Impact
------
Cursor isn't pointed the right direction with multiple screens with different rotations. This seems to only happen when the Desktop Icons extension is disabled (for instance in the default GNOME session).

Test Case
-----------

1) Use one of the GNOME Shell extensions app to disable the Desktop Icons NG extension.
2) Plug in a second monitor.
3) Open the Settings App. Open the Displays page.
4) Set one of the screens to have Orientation: Portrait Right
5) Move your cursor from one screen to the other. It only happens if there aren't windows open under the cursor so this is easiest to reproduce if your windows are all minimized.

What Could Go Wrong
-------------------
See the master bug for this update at LP: #1972726

Original Bug Report
-------------------
I have a multi-screen setup with one of the displays being rotated (Portrait Right in Displays settings).

Since upgrading to Jammy the cursor gets 90° rotated after being moved from a landscape to the rotated screen.

This seems to be happening only in Overview or if cursor is hovered over the desktop. Hovering cursor over the application window (e.g. Terminal) would reset the rotation; however, after being moved back to the landscape screen, the cursor gets rotated again (but now in an opposite direction).

This doesn't happen on Xorg and it wasn't happening on impish (wayland).
This doesn't happen if desktop icons NG extension is enabled.

Additional notes: sometimes the dead cursor copy stays near the screen edge after cursor is being moved to a different screen.

DING is a workaround because it is actually an app window that covers the whole desktop, mostly transparent.

[Vadym Abramchuck (abramzzz)]

Note: I just found the issue is only happening if DING extension is disabled. I've updated the bug description but didn't find a way to update the title.

Hi Timo,

Thanks for an update!

I can confirm the bug no longer happens with mutter (and friends, i.e. mutter-common, libmutter etc) 42.1-0ubuntu1 (installed from jammy-proposed). I'm not observing any other issues or side effects.
