Comment 33 for bug 1386721

This affects me too on Ubuntu Gnome 14.10 with Lenovo Yoga 13 and Intel HD 4000. Basic gnome animations are slow, or better said, they always get at least one lag during animation. I have to say that I played with unity and unity8, then uninstalled it.
ibus-gtk was installed so this was no fix for me. I am going to try Gnome Shell staging as suggested. Wanted to try it before anyway...
