I tried out your video, and had no issues with it on 1.3.  It played
silky smooth both when I double click the file, and on the timeline.
The underlying video editing framework has not changed (from 1.2.2 to
1.3.0), so this is very strange.  I would be sure you are not zooming,
panning, rotating, or any other effect which would "scale" the image, or
something like that.

Also, you might try reverting to version 1.2.2 and verify that the exact
same steps do not produce stuttering, etc...  Once we learn more about
this bug, we can update the status to 'confirmed'... if we can confirm
it. =)  Thanks!

Title:
  choppy playback on timeline

Status in OpenShot Video Editor:
  Incomplete

Bug description:
  I have tried out 1.3 a bit, and the first thing I noticed was that
  playback on the timeline is very choppy. Also the playhead "shivers"
  during playback. When I double click a fil in the Project Files area,
  it plays just fine. But it is not possible for me to edit anything
  like this. The same video files have been fine in previous versions.

  Linux Mint 9
  OpenShot 1.3 from PPA, upgraded via Synaptic
  Video files I have tried are motion jpg .avi, 640x480, 30 fps.
