            Bug ID: 60287
           Summary: GetCursorPos returns a stale position under
                    XWayland/Wayland after the pointer leaves Wine windows
           Product: Wine
           Version: 11.16
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED

          Priority: P2
         Component: winex11.drv

minimal reproducer

In a Wayland session, GetCursorPos() continues returning a stale position
inside the window after the cursor leaves all Wine windows and moves onto a
native Wayland surface.

This directly affects applications that poll GetCursorPos() and
WindowFromPoint() to detect mouse movement. For example, Plants vs. Zombies
uses a polling loop to handle cursor transitions. On Windows, it detects the
cursor leaving within about 20ms, but under Wine/XWayland, it never detects the
leave.

Wayland does not expose pointer coordinates once it leaves the surface and
enters a foreign window.

I've created a minimal reproducer. To compile, run:

```
x86_64-w64-mingw32-gcc -mwindows -o cursor_poll.exe cursor_poll.c
```

Run it in a Wayland session, and move the pointer out of the window at normal
speed. The status text should flip to OUTSIDE immediately, as on Windows.
But it stays INSIDE with a frozen position.

--- Comment #1 from Gabriele <[e-mail]> ---
Is this, somehow, related to when earlier I tried to record a game, using OBS
and OBS_VKCAPTURE variable, and the pointer got captured in the center of the
screen (with the option "capture pointer")?
Game running in wayland mode.
