I may have simmilar issue here when I restore my firexox browser. (after suspend mode gone wrong. switch on firefox and restore all windows)
I use few different windows of firefox at the same time. I try to organize/spread different firefox windows, for ex.: using ctr+alt+arrow down (move it down). After that when I am going back to the previous workspace the moved window appear back on the origin workspace. It looks like Ubuntu get confused about nummbering the workspaces. The window is positioned out of the screen (see attached file) ** Attachment added: "fd" https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1289820/+attachment/4082799/+files/fd -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1289820 Title: 'Move to Another Workspace' causes window to disappear Status in Compiz: Triaged Status in “compiz” package in Ubuntu: Triaged Bug description: When using the 'Move to Another Workspace' right-click option on a window, the window disappears from the current workspace, but is not present in any other workspace. It effectively is no longer accessible, though it can still be killed. Disabling workspaces does not cause the lost window to reappear, but setting the number of desktops to 1 in CCSM > General Options > Desktop Size > Number of Desktops does the trick and the window reappears. I am using Ubuntu 14.04 (latest updates as of 2014-03-07) and NVIDIA proprietary drivers. I do not experience this problem on Ubuntu 13.04.
