#383 previewing effects has high cpu usage [crash]

[ingwer]

first congrats to version 1.1

I noticed previewing effects has high cpu usage, up to 10 % on VM, and 2-5% on my host machine,

I even managed to crash the app, see attached log.

cheers

Thanks for reporting this!
I can't fix the CPU usage, the transitions are - I'm afraid - rather CPU hungry.
However, the crash I can fix.
So, thanks for reporting this.

Problem was the previewing of a transition that is at time '0' in the timeline.
Similarly, the preview of a transition at the end of the timeline had issues as well.

Both of these will be solved in the next release.
