Description Jakob 2021-02-27 11:14:48 UTC

SUMMARY
When I have something more in the timeline (2 clips, an image, a counter and an effect for each element), the program freezes. If I click on any icon, it does not react (so it is not highlighted as usual when I move the mouse pointer over it).

STEPS TO REPRODUCE
1. start a Kdenlive project
2. add a few clips (2), a picture, a counter
3. add an effect to each of the clips and the counter
4. try to work with it a bit more, for example by adding more effects
5. kdenlive freezes and does not work anymore

OBSERVED RESULT
Kdenlive freezes so I can't click on any buttons. The buttons are also not highlighted.

EXPECTED RESULT
I can work normally - Kdenlive don't freezes.

Please try with the current Kdenlive AppImage version 20.12.2 to see if there are any packaging issues https://download.kde.org/stable/kdenlive/20.12/linux/

I have just tried it out. Unfortunately there were no changes. After a few minutes (or the start of the program's internal video playback) Kdenlive froze again.

So I assume you have tested with the AppImage. Please update your Mint to the latest version. (And disable all GPU acceleration because they are not stable.)
