after using plain Arch for a few months I decided to switch to Antergos. But I got trouble with various video cutting tools like Openshot, KDEnLive or flowblade. All of them are using the MLT framework. Playback is always very jerky. Using melt via terminal makes no difference. In VLC and Totem playback is perfect!
Today I noticed using openshot via Antergos live via USB image works perfect! Installed clean and fresh antergos and got the same issue with current and LTS kernel as before.
There must be anything in Antergos live what is missing in my installed environment. I’m using Core i7 with NVIDIA GTX 560 (untouched nouveau-driver and nvidia-driver tested without difference).
Any hint would be great!
