I'll add that berend's suggestion (#11) fits my case. To solve, I inspected settings using gsettings and I found number-of-desktops set to "2". When I set it to 1 (which I believe is the default value) the problem went away.
Here's an example from console: # Find the keys I'm looking for. gsettings list-keys org.compiz.core:/org/compiz/profiles/unity/plugins/core/ ... hsize vsize number-of-desktops ... # Get the current value for number-of-desktops gsettings get org.compiz.core:/org/compiz/profiles/unity/plugins/core/ number-of-desktops 2 # Set my desired values for number-of-desktops, and number of workspaces. gsettings set org.compiz.core:/org/compiz/profiles/unity/plugins/core/ number-of-desktops 1 gsettings set org.compiz.core:/org/compiz/profiles/unity/plugins/core/ hsize 2 gsettings set org.compiz.core:/org/compiz/profiles/unity/plugins/core/ vsize 2 -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/885070 Title: "Move to Another Workspace" causes window to disappear To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/885070/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : [email protected] Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
