I have weird bug. When I watch FLV video, especially from Youtube, the Ubuntu starts freezing and glitching. Those bugs end with total freeze of the system and required reboot, which makes me quite angry
Finally it doesn't matter what app I use to watch a video. Either Totem Player or Chrome browser have the same problem.
I suppose that the issue is in the codec, but don't know how to check it or fix it. What can I do to sort it out?
