Comment 1 Florin 2017-02-23 13:46:31 UTC

I've noticed that kdenlive crashes when playing overlay effects like fade or dissolve when using GPU accelerated effects. I'm running NVidia proprietary drivers on a Quadro 4000.
I've deactivated GPU acceleration and no more crushes when running only on CPU power. 
Hope this helps.
