Comment:

 Unfortunately, flickering is an original game bug:

 Theora video file "audio/RosemaryIntroFinal.ogg" distributed with the game
 is corrupted according to ffmpeg:

 While playing the original game you can also notice flickering, that is
 not so intense, but happens on the same frames.
 While watching this video with VLC player I experience freezing at some
 frames.

 My guess is that some/most keyframes are broken and have transparent
 pixels that are rendered as white pixels by libtheora.

 NOTE: I there would ever exist a fixed version of the opening video, it
 could be placed as "audio/RosemaryIntroFinal.ogg" near data.dcp, so that
 ScummVM would play fixed version instead of video packaged with the game.
