@Kubuntiac what video file format are you using? Does the video file have any
strange properties? Does it play back properly in VLC and other media players?
Can you seek it properly or does seeking cause freezes or A/V desync?
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
I can confirm this or a similar issue with recent git, however only when using
an apparently broken mkv video* and apparently only a low zoom levels (1 or 2).
The final result of the issue is that Kdenlive freezes after clicking around
the timeline less than 10 times.

- The issue can be reproduced when not recording a screencast as well.
- Rewriting the container (ffmpeg -i in.mkv -c copy out.mkv) does not solve the
issue.
- Reencoding to mp4 solves the issue. The video is still broken somehow
(clicking in the first half, will start the music at the beginning, no matter
where to click and it will show a static image but the right half is useable
and it does not cause a freeze.
*The broken-ness of the video appears to be that audio and video are somehow
out of sync perhaps and video players either don't play back anything for a
while but skipping seems to help and seeking back only allows to go back to
about 3m40s of the total >9m of video. Here is the broken pinball.mkv file:
