SUMMARY
Topic -- which here is weirdly labeled "summary" too -- says it all.

STEPS TO REPRODUCE
1. Add two clips to the time line
2. Scrub into one
3. Turn some Overlay in the Project Monitor on
4. Zoom in
5. Move viewport into some direction (so that the center of the clip is not displayed in the center of the viewport anymore)
4. Switch to the second clip

(Maybe it's already enough to click out of the clip and click inside the same again.)

OBSERVED RESULT
Overlay gets aligned to the viewport of the window, means for example that a center crosshair is in the center of the window/viewport.

EXPECTED RESULT
Overlay should be aligned with the frame of the clip, meaning if the the viewport of the Project Monitor is moved aside so should be the overlay. (Center of Frame != center of viewport.)

SOFTWARE/OS VERSIONS
Windows: 7

PERSONAL COMMENT
Makes alignment a horror and leads to HEAVY confusion. With the level/stage of "complexity" kdenlive reached I would go so far and call it a basic function. Meaning: I would like to bump severity to at least "major" though programmatical its not critical obviously.
However, guess it should be an easy fix ... right?
