QShapedPixmapWindow is used as a drag-and-drop icon. This caused two roles (wl_data_device-icon and wl_shell_surface) to be assigned to the same surface, resulting in a protocol error. This bug hasn't been encountered before because QShapedPixmapWindow sets X11BypassWindowManagerHint, which was previously used to determine whether to create a shell surface or not.
