Bug ID: 56159
           Summary: game blocks ~30 seconds, continues and then hangs, in
                    "TKKG 1" (EN: Jennifer is Missing, DE: Katjas
                    Geheimnis - Tivoli)
           Product: Wine
           Version: 7.14
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: win32u

Since below commit game shows on black background a frame with black inside,
for around 30 seconds, then continues the first screen normally without sound.
Then hangs at the "second" screen "Tivola".

A regression test needed applying de3bc7d5119 and 7748c76e359 at each step
because of #56152.

This led to:
commit a53330b9c137388f3b9e78f2aacffa3fc1692d6e

    win32u: Use syscall interface for message functions.

Unfortunately this commit does not revert on top of current git.
