mfmediaengine:mfmediaengine - test_TransferVideoFrame() sometimes gets a 56%
diff on Windows 10 1607+:

mfmediaengine.c:141: created

mfmediaengine.c:1313: Test failed: Unexpected 56% diff

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

This failure is quite rare, happening a bit under 1 per month:
* 2022-10-14 win21H2_fgtb-w10pro64-64
* 2022-11-23 win21H1_newtb-w10pro64-ar-64
* 2022-12-09 win21H2_newtb-w1064v21h2-64
* 2023-03-02 win1607_newtb-w1064v1607-64
* 2023-04-20 win1607_newtb-w1064v1607-64
* 2023-06-01 win1607_newtb-w1064v1607-64
* 2023-06-14 win21H1_newtb-w10pro64-hi-64

Note that it happened systematically on the debiant VM for a while but that was
probably because of a GStreamer issue (2022-11-18..2022-12-16, maybe related to
vaapi issues). What's interesting is that it was the same "56% diff" error. So
it's possible the test completely fails, gets a zero-filled BMP that still
gives this 56% diff error.
