> SUMMARY
> ***
> When editing a clip using the Transform tool, mostly when moving
> (translating) a keyframe, sometimes the scaling/translation components of
> the keyframe get lost and simultaneously all red keyframe dots on the
> preview vanish.  This most commonly happens when using the direct entry
> boxes in the tool (e. g. horizontal and vertical position).  I use the
> mousewheel to move the frame; while spinning the wheel, I observe all of the
> keypoints vanish.  In case it matters, I always lock aspect ratio.
> 
> Undo does not restore them.  If I save the project, I observe that there are
> no keyframes in the translation/scaling list that were inserted prior to
> them getting lost, but rotation components are there.  If I reopen the
> project, the keyframes show up in the timeline, but the positions are gone. 
> Needless to say, this results in the loss of a lot of work.
> 
> If I save the project after every keyframe edit, this does not happen.  It
> otherwise does not happen predictably and there's no specific reproducer
> case.  Perhaps the fact that saving the project constantly suppresses this
> behavior gives a clue.
> 
> Another effect that may or may not be related is that a keyframe added after
> this will be set to Discrete mode even though I have not to the best of my
> knowledge requested that.
> 
> This happens at least for the last several major versions.

> STEPS TO REPRODUCE
> 1. Open kdenlive (on a new project)
> 2. Add a clip
> 3. Open the Transform effect, and start adding keyframes

> OBSERVED RESULT
> On occasion, all keyframes vanish
> 
> EXPECTED RESULT
> Keyframes do not vanis.
