Ubuntu 11.04, Compiz 1:0.9.4+bzr20110606-0ubuntu1~natty2 (compiz-core)

Adding or removing a second monitor can move windows between adjacent workspaces (presumably because the sizes of the workspaces change). I.e. if I add a second monitor to the right of the primary one, windows on the second (right) workspace may move to the - now wider - first (left) workspace. If I remove the second monitor, windows in the right part of the first workspace may move to the second workspace, as the workspaces get narrower.
This is highly annoying. (It didn't happen with my previous system, Ubuntu 10.04 without Compiz.)

This bug may be a duplicate of #255186 or #151949, but since these have been long closed without ever getting resolved, I'm opening a new one.
