Public bug reported: Hello all, I have a video issue with my VAIO laptop. When I play any video (mp4, mkv, ...or any streaming video) with VLC, Totem, Kaffeine (or any other player), some horizontal freeze occurs. It is very light and you have to look very carefully to notice these freezes! I am using Linux Mint 17.2 MATE, but I also noticed this issue in Linux Mint 17 MATE, and LMDE 2 Betsy on my laptop. I also tried to install Lubuntu 15.04 just for a try and I also noticed the same freezes, whereas the same video is smooth on another desktop PC. The same video is also smooth on Windows 7. I also tried to install the latest Intel Graphics driver, and to update the kernel....and still the same issue.
So for me, after these tests, the root cause is related to my laptop graphics card driver. Can you help to solve it please?
