SUMMARY When setting Krita to start with the Session Manager, pressing the close button will continue to launch the main window. This was a workaround for Bug 431755. After a quick exchange on the IRC it seems unclear if this is the desired functionality of the Close button on the Session Manager, though. While this definitely is preferable to having a useless background process (that keeps Krita from launching at a later point) I would make the case that the Close button should really abort the launch and terminate all processes related to Krita.
