Premiere timeline skips backwards a few frames during playback
Example:
I haven't opened this project in 5 months or so (when it was working fine). When I opened it today, in Premiere 12.1.2 (Build 69), it upgraded the project, and seemed fine, except playback skips back. For example, after 10 frames of playback, it skips backwards 5 frames, etc etc, giving the video playback a stutter. You can see the skip back not only in the video, but hear it in the audio, and see the play head skip backwards.
This also occurs when previewing a clip not on the timeline.
