           Summary: d3d9:device - test_wndproc() sometimes gets an
                    unexpected WM_DISPLAYCHANGE in Wine
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2

d3d9:device - test_wndproc() sometimes gets an unexpected WM_DISPLAYCHANGE in
Wine:

device.c:4349: Test failed: Expected message 0x7e for window 0x1, but didn't
receive it, i=1.
device.c:4359: Test failed: Got unexpected hr 0x88760869.

https://test.winehq.org/data/patterns.html#d3d9:device

Where 0x007e == WM_DISPLAYCHANGE.

The second failure is not always present but does not seem to happen without
the first one so they are probably related.

These failures:
* Happen on my Debian 11 + Intel + KDE box (fg-deb64)
* Don't seem to happen on my Debian 11 + QXL + fvwm + single monitor VM
* Happen on the TestBot's Debian 11 + QXL + fvwm + dual monitor VM
* Happen on the TestBot's Debian Testing + QXL + fvwm + dual monitor VM
  (very rarely but two wow64 instance have been seen)
