Description qubodup 2015-12-03 10:16:29 UTC

catalyst-hook 15.9-6
catalyst-libgl 15.9-2
catalyst-utils 15.9-2
mlt 0.9.8-3
qt5-base 5.5.1-3
kdenlive git describe --tags --always
v15.11.80-53-g0918054

Possibly hard to reproduce.

Steps to reproduce
1. Start kdenlive
2. Import an mp4 video
3. Drag video to timeline
4. Switch to overwrite mode
5. Cut video into 3 pieces
6. Move clips around quickly, in combination with using ctrl+z (undo) quickly

Expected results:
1. Actions happen instantly, delayed or ability to take action is taken away while the UI updates.

Actual result:
1. I get error messages that undo can't be done and the clips are changed in a manner that was not present in the history or Kdenlive freezes or Kdenlive crashes.
