Scaled window keeps moving in the spread mode (switch between windows of same process)

[Lain_13]

1. Open this page: http://oss.jodi.org/vv.html
2. Allow vv1.html window to pop up if Firefox blocked it (there are 4 jumping windows in total, totally harmless but hard to close).
3. Click on the Firefox button on Unity panel.

Expected result: image of previously jumping window stands still and could be either focused or closed using closed button at the corner.

Actual result: window keeps jumping from it's position and it's almost impossible to close it. The only way to close it is to Alt-Tab to it and press Ctrl+W.

Additional information: In GnomeShell this window does not jump from it's place in the spread mode.

It's not very noticeable on the screen captured video but look at the beginning and in the end - it's jumping in the spread mode. It's like this all the time and doesn't actually stop as you can see in the video. Probably jumps just synced with capture speed and screen capture program made screenshots at the moments when window were returned back to it's place.

Confirmed but low priority for now. Unless there's a more common or day-to-day use case.

Thank you for taking the time to report this bug. Since, I can reproduce this problem in other DEs, I believe that it's not compiz related. Therefore, I changed the status to Invalid.
