Description

Evince (and other Gnome gtk3 applications) cannot be raised or lowered by clicking on the title-bar, and cannot be shaded by clicking or scrolling on the title bar, even when shade is selected as the title-bar double-click action in Xfce settings.

I understand that these applications use "client decorations," but I don't understand how much xfwm4 is being "cut out of the process". Is it completely out of the window manager's hands? Or can something be done to improve consistency between these apps?

If it is impossible to change xfwm4 to allow these traditional WM capabilities for these applications, can you suggest where is the next logical place to report this problem?

Alternatively, is there a way to use these applications with xfwm4 that respects Xfce window manger settings?
