Ubuntu – Close window in window overview

For 14.04 (Trusty Tahr) it could be disabled with the command:

gsettings set org.gnome.desktop.wm.preferences action-middle-click-titlebar 'none'

Restore original state:

gsettings set org.gnome.desktop.wm.preferences action-middle-click-titlebar 'lower'

Also, the following variants are possible:

gsettings set org.gnome.desktop.wm.preferences action-middle-click-titlebar 'toggle-shade'
gsettings set org.gnome.desktop.wm.preferences action-middle-click-titlebar 'maximize'
gsettings set org.gnome.desktop.wm.preferences action-middle-click-titlebar 'toggle-maximize-horizontally'
gsettings set org.gnome.desktop.wm.preferences action-middle-click-titlebar 'toggle-maximize-vertically'
gsettings set org.gnome.desktop.wm.preferences action-middle-click-titlebar 'minimize'
gsettings set org.gnome.desktop.wm.preferences action-middle-click-titlebar 'shade'
gsettings set org.gnome.desktop.wm.preferences action-middle-click-titlebar 'menu'

But the bug is still there, option from the Google Chrome Settings "Use system title bar and borders" could lower the impact...

You can also use the Alt-` shortcut to switch between open windows of the same application. It's not exactly a solution, but it might help you get back to your terminal faster. I typically use Alt-Tab to get to the terminal application and then switch to whatever window I need.

You could also use scale function to show all your windows and then click the window that you want. By default, I believe the shortcut is Super-W, but it can be changed in the compiz settings manager under Window Management->Scale->Bindings->Initiate Window Picker for All Windows

Hope this helps!
