Description Johannes Wuensch 2016-10-20 17:36:02 UTC

Moving multiple clips horizontally is handled wrong by undo. If you undo your move, it visually looks correct as the clips in the timeline jump back to where they were before. But if you try to playback it, you will notice, that under the hood, they are still where they were before the undo. If I now save and close the project and open it again, the clips are where they were before the undo.

I also quickly recoreded a video where you can see what I mean:

I'm using Kdenlive 16.08.2

I tested with the AppImage of 16.12 again. Bug is still there, nothing changed...

I confirm this bug, happens without applying any effect.

This timeline corruption bugs are the reason we are doing the refactoring. After it is finished besides this problems will be gone and the great new features will be shining. My workaround for now is to not do this things that trigger the corruption.

Seems to be fixed in refactoring branch.
