Bug ID: 52518
           Summary: [quartz] Changes to playback speed show no effect
           Product: Wine
           Version: 7.1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: quartz
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Unity games supporting a 0.5x, 1.0x, 2.0x playback speed for quartz powered
videos show no change in actual playback speed. A request of 2.0 is visible,
but immediatly discarded.

The logs show e.g. on pressing 2x:
011c:fixme:quartz:MediaSeeking_GetRate (00AF1B30/00AF1B3C)->(2.0): stub !!!
Immediatly followed by:
011c:fixme:quartz:MediaSeeking_GetRate (00AF1B30/00AF1B3C)->(0068F550): stub
!!!

which is probably the defaulting in

back to 1.0
