Running MC 8.9.2 (although I had the same issue when I just tried 8.6.3)..
All of a sudden, I cannot play back clips in the source monitor or in the timeline.
When trying to play back clips in the source monitor (AMA-linked H.264 or transcoded DNxHD 175 when testing this issue), the video and audio will stutter. I can skip ahead but, at random points, the playhead will jump back to the atart of the clip.
When trying to play back in the timeline, video and audio play okay but, again, the playhead will jump back to the start of the sequence randomly. At this point, it automatically enters trim mode.
I have tried various setups with keyboards/mice/etc. and it always exhibits the same behavior.
The issue has rendered the whole application completely unusable.
Could a graphics card update be causing this odd behavior?
Any insight into a possible cause woulde be much appreciated.
