Timeline UI behaves erratically

*What is your operating system?
OSX 10.15.5, macbook pro

What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
20.07.11

Can you repeat the problem? If so, what are the steps?
dragging clips across the timeline feels like mouse events are registering at a different place. clips jump tracks, play head moves instead of clips, clips move at a different rate than the mouse, position flickers. tends to destroy recent edits, which don’t undo.


screen recording:

  • dragging clip shows alert from different track.
  • dragging at different rate than mouse
  • end position flickers
