title: Qt Creator adds an invisible character in Fake Vim mode when it loses the focus
body: <p>As you may know you can activate <strong>Fake Vim</strong> mode in <strong>Qt Creator</strong> with Alt+V, Alt+v. But when I activate it in my Fedora machine, I see kind of strange behaviour.  Every thing is OK but when I switch to another program or even when I open a new window in creator ( I mean when editor loses the focus ) a new invisible character is added to my editor and I can't compile the source code anymore! You can see this situation in the picture bellow. Is it kind of bug? When I delete that character every thing becomes normal.<br>
