While the window is shaded (which is not really shaded since there are no window decorations for it -- it's actually missing), it is missing from the window list for an application, which makes it impossible to switch to.
The only way I see to reclaim the lost window is to close or move all other windows of that app so the missing window is the only one left on the workspace, then click on the running app's icon again. Then, the running app is still not listed, but clicking on it raises it somehow. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

When I click to top of the window, it rolls up and disappears. A "ghost" outline of the window appears and the only way to get the window back is by using Alt-tab. Sometimes, when reselecting the window using Alt-tab, Ubuntu freezes (crashes) and an internal error is generated. It seems to be related to Compiz but I'm not sure. An error report was generated and sent. Description: Ubuntu 14.04 LTS (64-bit) Release: 14.04 unity-tweak-tool 0.0.6ubuntu1 I expected the window would "roll up" and I'd be left with the window's top bar like with previous versions of Ubuntu.
