Hello,

I am experiencing choppy video playback, once I upgraded from 16.04 LTS to 17.04. Since the upgrade process passed through 16.10, I am not certain when exactly the problem was introduced. Almost every video I play (with VLC, but also when trying to use kdenlive) begins good, but eventually starts to stall the image (while the audio is playing), then jumps to other frames etc. The stalling of videos within kdenlive is even worst (both video & audio). How can I investigate what is causing the issue and eventually fix it?

Any help will be apprecited.

I didn't find the right solution from the Internet.
