I'm wondering if anyone else has seen this.

I have three virtual desktops aligned in a horizontal row. In the middle desktop I have only a single application window. I have keyboard shortcuts mapping to navigate between the desktops. Obviously, I never use the up/down arrows because I only have one row of workspaces.

Here's the problem, which only started to happen after I installed 12.04.1: When I rapidly hit to go from workspace 1 to workspace 3, the window on workspace 2 gets moved to workspace 1.

I have checked using both Unity and Gnome3, and the behavior is the same under both.

If I change back to the default workspace setup (a 2x2 grid of desktops) things seem to settle down (i.e., no wandering windows). Not every type of application window behaves the same way. I couldn't get a Chrome browser to jump from 2 to 1, but both Terminal and Terminator exhibit the behavior.

Any thoughts? Better workarounds?

Thanks in advance.
