    Resolution Note (fix version 2021.1):

    Fixed in 2021.2.0a3. Support of high range of speed change on OSX hits an Apple AVFoundation issue where network requests are incorrectly sequenced. Disabling high range support for network sources. Smooth playback will now only be possible for <= 2x and beyond this only keyframes will be shown.
