Bug ID: 53265
           Summary: mmdevapi:capture - test_capture() has timing-related
                    failures on Windows
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mmdevapi
          Assignee: [e-mail]
          Reporter: [e-mail]

mmdevapi:capture - test_capture() has timing-related failures on Windows:

capture.c:282: Test failed: Position 1719 last 896 frames 448

https://test.winehq.org/data/patterns.html#mmdevapi:capture

The failures happen randomly but frequently on Windows 8 to Windows 10 1809.
However, because the message includes a duration, it is prone to cause false
positives (see also bug 53126 for a similar failure in mmdevapi:render).

Furthermore mmdevapi:capture has other systematic failures on Windows 10 1909+
that probably just mask this one (see bug 53264). So one should assume that
this timing-related failure impacts all Windows 10 versions.
