Getting very weird glitches that I've seemed to narrow down to a nested sequence with an audio track. When a timeline has a nested sequence in it, suddenly when I use the cursor to move a clip, there is no preview of where I'm dragging the clip. The clip stays in the place it currently is, and the timecode changes, but I can't actually see where I'm dragging the clip on the timeline until I release my mouse button and drop the clip. Other people have written about this issue and I don't understand how it's still a bug.
