I tested with a few video files (.mp4 and .mkv) , everytime I take a screenshot with Smplayer the movie will break up with little flashing black squares and need to restart Smplayer. The screenshots are good though. I am using Smplayer 14.9.0 (svn r6887) from rvm ppa on Ubuntu 15.04 64 bit, with mpv as the backend. Graphic card in Intel ironlake mobile.
I am wondering if there is any setting I need to adjust (can't find any)
Thanks.
P.S. For testing I just took a few screenshoots with vlc and there was no breaking up.
