QVideoWidget rendering video incorrectly on macOS Monterey

QVideoWidget on v6.5.0 seems to render pure black in videos (what may be encoded as transparency) as white.

See the examples images (attached) showing the Media Player Example (to which I have made no code changes). The same rendering error occurs with both the "darwin" or "ffmpeg" media backend on 6.5.0 and not at all on 6.2.4. I can tell the backend is indeed different between the darwin/ffmpeg screenshots because of the different metadata included (lower red arrow).

The same error occurs in the "Video Widget Example," (in 6.5.0) but NOT the "Video Graphics Item Example" (in any version, with either backend).

This leads me to believe the issue is likely with QVideoWidget rather than QMediaPlayer of the ffmpeg implementation.

Thanks for looking!
