    Description

      If application project has "webenginewidgets" QT module dependency:

      QT += webenginewidgets

      then QMediaPlayer fails to correctly playback any video file (playback is actually started, sound correctly played, but AVFoundation plugin returns empty or black QVideoFrames to media player) on macOS BigSur 11.

      Following warnings/errors could be seen in log:

      [OGL] CoreAnimation: rendering error GL_INVALID_ENUM

      Same project/code works OK on Windows 10 with WMF plugin enabled and on macOS High Sierra 10.13 (didn't try on macOS Mojave 10.14 or Catalina 10.15).

      Archive with sample project code, reproducing problem, attached.
