Ok, triggered issue running Lubuntu. Ran GtkPerf on a freash startup with no other apps running. Started Firefox, browsed news sites (guardian, bbc). Started Totem, played local video. Started Evince, opened local PDF form which triggered the issue.
Vidoe slows down and gets out of sync with audio. Moving desktop windows around becomes really slow. PDF scrolling is also very slow. Opening other sites in Firfox takes a long long time to load and script heavy pages pop up constant "unresponsive script" warnings. Shut down Firefox, Totem, Evince. They are slow to respond to clicking on the X. Ran GtkPerf again. Noticiably slower in everything. Before, Total time: 8.91 After, Total time: 67.49 Again, this is all under Lubuntu, not Unity or Gnome Shell. ** Attachment added: "Test result under Lubuntu" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1189645/+attachment/3723028/+files/GtlPerf-Lubuntu -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1189645 Title: General lag under desktop environments To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1189645/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
