Bug ID: 54304
           Summary: user32:input - test_GetRawInputBuffer() sometimes gets
                    unexpected GetRawInputData() success in Wine
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: user32

user32:input - test_GetRawInputBuffer() sometimes gets unexpected
GetRawInputData() success in Wine. This results in a group of 3 failures:

input.c:2287: Test failed: GetRawInputData succeeded
input.c:2288: Test failed: GetRawInputData returned deadbeef
input.c:2421: Test failed: Spurious WM_INPUT messages

See https://test.winehq.org/data/patterns.html#user32:input

The first known instance goes back to 2022-08-29 and there has been roughly 2
failures per month since then with a two months gap (October & November). That
makes it hard to know when this failure really appeared.

Note that the 'spurious WM_INPUT messages' failure also appears on Windows. See
bug 54053.

--- Comment #1 from François Gouget  ---
This can also happens on Windows:
* This happened 12 times on w8adm between 2022-12-09 to 2023-01-13 but then it
stopped.
* This happened once on w10pro64-ja (64-bit) on 2023-01-06.
* This happened once on w7u-es on 2023-03-20.

I think this points this issue being caused by an external factor that can
happen on Windows just as well as in Wine, probably a side-effect of some other
test.
