My understanding is that the problem doesn't necessarily lie in Intel graphics driver, if that would be the case, sluggish performance would affect desktop as a whole, regardless of applications currently running. At the moment, my 14.10 Gnome desktop is perfectly smooth until I launch certain applications like Google Chrome or Image Viewer. Gedit also caused this issue until I upgraded it to 3.12.2 from gnome3-team's ppa - now runs without a hitch. That makes me think that these applications are rendered using different library/method which is not accelerated by graphics driver - that's how in laymans words I would describe my understanding of the case.
I have also reported #1385764 which has been marked as duplicated of this bug, where I explained the issue further. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
