           Summary: [Gtk] drag and drop has black background without
                    composition
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: arno at renevier.net


Hi, when dragging some text, a popup window with 0 opacity is created. It is then set as the drag icon with gtk_drag_set_icon_widget. While this gives a nice transparent result an a desktop with a compositor, it gives a black background when there is not compositor. So, if the text is black, it is not readable. And if the text is white, it's ugly anyway. May be we could use gtk_drag_set_icon_pixbuf as mozilla does (or gtk_drag_set_icon_surface when available to avoid a cairo/pixbuf conversion). This api decompose image into transparent/non transparent rectangles and use Xshape to make the transparent rectangles actually transparent even without a compositor.
