Hi Jason, Thank you for taking the time to report this bug.
This is most likely a problem in Compiz. I'm trying to tackle issues like this. A couple of questions. 1) Are these windows that get shifted to other workspaces maximized windows? 2) Are you doing any sort of monitor hotplugging? 3) Is the machine suspending and then resuming? Thanks! ** Changed in: unity (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

I still have 8 - but most are empty There is no error, and they (say) go from 5 in use to (say) 3 in use - not a total collapse and not showing any app dependency. eg I may find firefox and thunderbird in the same workspace and another time find remmina sitting underneath some terminal shells The only extra piece of info is that it appears to only happen to the workspaces that I'm not currently in. ie I don't see this happening in the current one - always another one. Sort of Heisenburg's uncertainly principle at work!
