(Get the code!)
I'm using Ubuntu 12.10 with an AMD A8. When I use either an nVidia 460 or AMD 7870 I experience this issue (have tried many drivers with both of these cards, including the latest beta drivers). I have tried to make a video of the issue, unfortunately my phone's camera doesn't capture video at a high number of frames per second, so the issue doesn't look that noticeable in the video:

SuperKey + S and SuperKey + W are really stuttery in 2560 x 1440 mode. I've also noticed that is doesn't occur on my laptop (Intel HD 4000 integrated graphics) when it's only driving a single monitor (even at 2560 x 1440), but does occur when I connect a secondary monitor (the laptop screen is 1920 x 1080, the secondary monitor is 2560 x 1440).
