I can confirm the observations made by Dawid Lorenz I tried replicating the actions in the video he posted in his own bug report, and found the results to be the same.
- Opening the image viewer made desktop switching noticably slower. - Launching Google Chrome brings about very noticable performance changes overall - Upgrading my Gedit from 3.10 to 3.12 eliminated the issue with slow performance in the text editor Video Link: http://www.youtube.com/watch?v=0LhKhdgKHiQ Repository: https://launchpad.net/~gnome3-team/+archive/ubuntu/gnome3 Definitely seems that at least part of issue bight be in drawing/updating of gnome 3.10 applications However, I've noticed: - Opening a gnome terminal window (NB: Version 3.12) also brings about the sluggish performance in desktop switching So I'm not sure the issue can be solely attributed to the the 3.10 vs. 3.12 changes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1386721 Title: Graphics Slow After Upgrade 14.04 - 14.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1386721/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
