'Move to Another Workspace' causes window to disappear

Thank you for your bug report, is that still an issue? Does it happen every time? What screens/workspaces configuration do you use?
I can't confirm the issue here

Yes, it is still an issue and happens every time. I have been dealing with it since I first installed 14.04 back in early January 2014.

It happens whether I use System Settings > Appearance > Behavior > Enable workspaces, or manually configure workspaces using CCSM > General Options > Desktop Size (which I normally do since I prefer a flat horizontal workspace to avoid windows crossing workspaces).

I should mention that the window disappears even if I send it to the workspace it is already on.

I could not reproduce this issue in a fresh install of Ubuntu 14.04 in VirtualBox, so it may be specific to my GPU drivers or compiz config.

Status changed to 'Confirmed' because the bug affects multiple users.

It's estimated to have a moderate impact on a large portion of Ubuntu users.

I've been looking at this and it seems this occurs when setting ccsm->General Options->Desktop Size->Number of Desktops to some value other than 1. I'm thinking that setting may not be needed anymore, but I still need to investigate.

Yup that's what I did. Changed that back to one and my test window popped up! i noticed something else while testing that, don't know if its related. I've noticed that if you have the same window open on different desktops the launcher spread can't see the ones on other desktops.

Hi Corey,

Regarding the Spread on windows on different workareas, it is by design to only show windows in Spread for the current desktop.

I too can confirm that setting the number of desktops to 1 in CCSM fixes the issue.

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)

I am using 4 workspaces. I have changed nummbergin (swap workspace 3 with 4) and also I have changed shortcuts for getting to workspaces: I use alt+1, alt+2 to get to desirable workspace.
Thanks

It seems the automated message did not reach here.

Reproduced in trusty following the test case in the description. After installing compiz from precise-proposed, the option is gone and the Send to Workspace actions no longer appear, regardless of what it was set to before. Marking verified.
