'Lagging' when dragging timeline cursor

See attached video...

Whenever I drag the cursor over a clip on the timeline it lags or seems to jump back.
Is this something everyone has or is it wrong video settings on my part or so?

This is the result of a recent change I made. The cursor shows which frame is displayed by MLT in the project monitor. The result is as you said a bit "lagging" when seeking, but provides a better feedback when playing the video...
