SUMMARY
Using the Rotoscoping effect, the selection outlines do not align with the
shape/selection.
Applies to animated and static reotoscoping.

Note: When animated, if you move/wiggle the selection, the offset may
disappear.

STEPS TO REPRODUCE
1. Enable monitor "Show Edit mode".
2. Add video clip to timeline + color clip on top.
3. Add rotoscoping effect to color clip.
4. Make a selection on color using rotoscoping.
5. Observe offset.

-OPTIONAL-

6. Animate rotoscoping, ~5 frames at a time ( 3- 4 keyframes).
7. Return to first keyframe - (everything aligns).
8. Jump to next keyframe - (notice offset).

OBSERVED RESULT
The (red) outline of the selection/shape does not align with the Rotoscoping
selection outlines.

EXPECTED RESULT
The (red) outline of the Rotoscoping's selection should align with with the
selection/shape

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: 
KDE Plasma Version: 
KDE Frameworks Version: 6.9.0

ADDITIONAL INFORMATION
In my experience, when animated - a simple wiggle of the selection restores the
alignment.
Error seems to occur on smaller selections.
Error doesn't always occur.
