AFAICT, they all lead to a similar amount of hang checking under graphics load. The details: my test consists of running three glxgears instances and then opening up firefox and trying to watch a youtube video. Of course, this is not something I generally do but it does seem to generate GPU hangs so it's a good test. In some cases, simply using compiz transitions was sufficient to get a hang, once the glxgears processes were running. In all three tests with the git drivers, I saw 4-5 hangs in a few minutes. All of them recovered. I then downgraded the drivers, restarted and performed the same test: no hangs at all.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
