Comment 9 for bug 1080947

I'm here from bug 1007857. I have tried to make a video of the problem, but the stuttering doesn't look that bad in the video. I think my phone camera doesn't record at a high enough refresh rate:

In short, when I run on a single monitor (a Dell U2711 at 2560x1440) using either an nVidia GTX 460 or AMD Radeon 7870, dragging windows around near the top bar or the Unity Launcher results in very stuttery movement (it's not fluid).

The problem is not noticeable on my laptop which runs an Intel HD 4000 integrated graphics. With the Intel HD 4000 everything feels buttery smooth and super responsive. I did, however, find that with two monitors (one set to 1080p, the other to 1440p) that some animations were jerky (such as SuperKey + W and SuperKey + S).

Just adding my observations here in case it helps somehow.
