[Cin] Audio-video desync in preview composition when applying F_atadenoise

[Phyllis Smith]

If rendering is correct while playback is not, it could be the OpenGL
driver used in playback.  Rendering ALWAYS uses software and is not subject
to the vagrancies of OpenGL.  With the test I did, I could not detect a
playback error when using OpenGL.  Stefan, you can test this theory by
changing Settings->Preferences->Playback A driver to X11 instead of
X11-OpenGL (that is assuming you currently have it set to OpenGL).  It
would be interesting to know for sure if F_atadenoise will then be in sync.

When applying F_atadenoise I notice that the audio and video in the
> compositor upon *playback* is desynchronised. Rendering is not
> influenced, audio and video in the output file are in sync.
