Bug ID: 404938
Summary: kdenlive cornerswidget not displaying lines and
markers correctly
Product: kdenlive
Version: 18.12.1
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Effects & Transitions
Assignee: vpi...@kde.org
Reporter: renegodb...@yahoo.com
Target Milestone: ---
SUMMARY
The cornerswidget (ex. frei0r.c0rners) GUI does not track correctly.
STEPS TO REPRODUCE
1.add c0rners effect on a clip (10 sec is enough)
2.create a small "window" near the top left of screen.
3.add keyframe at end of clip and reposition the corners near bottom right.
OBSERVED RESULT
when playing or stepping frames with the effect lines and markers in view, the
position(s) of the "c0rnered" element is/are correct but the lines/markers
drift progressively away from the element. The offset seems proportional to the
magnitude of the displacement (cumulative rounding error?).
On the last frame (or near the end where the offset is visible), if you try to
move one of the markers, they all snap to their correct positions.
The error is only in the GUI of the effect, if you position your corners on
reference details of the background, the effect is composited at the right
place, only the red lines and markers drift away...
EXPECTED RESULT
perfect match!...
