To demonstrate data loss, just open a new application and roll up the window. Then use alt-tab to get to this window. On my machine the whole session get killed and I'm logged out! So I don't only lose the one application, but all open files! (Tried with Thunderbird and AisleRiot Solitaire under Ubuntu 14.04.3 LTS)
Workarounds: To disable the shortcut: gsettings set org.gnome.desktop.wm.keybindings toggle-shaded "['disabled']" To enable the shortcut again: gsettings reset org.gnome.desktop.wm.keybindings toggle-shaded To disable the mouse-action if you had it like me enabled on double-clicking the titlebar: gsettings reset org.gnome.desktop.wm.preferences action-double-click-titlebar To enable it again: gsettings set org.gnome.desktop.wm.preferences action-double-click-titlebar 'toggle-shade' -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity in Ubuntu. https://bugs.launchpad.net/bugs/1313446 Title: window disappears on toggle shade Status in Unity: Confirmed Status in unity package in Ubuntu: Confirmed Bug description: I used Unity Tweak Tool to enable Toggle Shade using middle click. 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.
