            Bug ID: 508818
           Summary: Rotation angle of transition incorrectly stored when
                    using drag handle
    Classification: Applications
           Product: kdenlive
      Version First 25.08.0
       Reported In:
          Platform: Kubuntu
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: Audio Effects & Transitions
          Assignee: [email protected]

  Target Milestone: ---

SUMMARY
When a transition is applied to a clip and it is rotated using the rotation
drag handle (the circle above the center) in the project monitor, the angle
shown (and actually applied) in the effect stack is incorrect.

STEPS TO REPRODUCE
1. Freshly start kdenlive
2. insert a clip
3. add the transformation effect to the clip
4. go to the project monitor and rotate the frame with the mouse using the drag
handle within the project monitor, let's say about 45°
5. observe the value of the rotation in the field within the effect stack.

OBSERVED RESULT
The stored rotation will be a really small amount, i.e. something between 0 and
3 degrees with some decimals. The rotation actually applied is exactly this
very same value, although the red frame in the project monitor shows different.
Move the cursors in the timeline back and forth to see.

This does not happen again, i.e. if you drag it a 2nd time, the value will be
corrected.

I furthermore observed that this rotation value will be applied to other
transitions "in the past" of the timeline. Unfortunately I don't yet know what
exactly to do to reproduce this 2nd side effect.

EXPECTED RESULT
Represent the exact same value as in the project frame.
