Title:
Periodically video will freeze for no reason at all and no specific
time between freezes.
Status in linux package in Ubuntu:
Confirmed
Bug description:
What I expect to happen is the video to not freeze every so often.
What happened is that the video froze. This has been going on for over a year. It doesn't matter if I have any applications open such as Evolution or Firefox. It could happen any time during the day when I'm working on the computer or during the night when it's the most idle. Once the video freezes the cursor can still be moved around the desktop however clicking on anything does not work. During this time all background process and cronjobs continue to run.
