Ubuntu – Gtk-Message: Failed to load module “overlay-scrollbar” Ubuntu 17.10

17.10gtkoverlay-scrollbarsqt-creator

I run application in reinstalled Qt Creator 3.5.1 (opensource)
Based on Qt 5.5.1 (GCC 4.9.1 20140922 (Red Hat 4.9.1-10), 32 bit)
And the building is successful.
But also there are warnings:

Gtk-Message: Failed to load module "overlay-scrollbar"
(untitled01:20644): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",
(untitled01:20644): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

This solution doesn't help
and sudo apt-get autoremovetoo

Another solution talks about gtk2-engines-pixbuf package
but what about gtk3?

Do you know some correct idea?

In my computer with Ubuntu 16.04, I solved it installing the package overlay-scrollbar-gtk2:

sudo apt-get install --reinstall overlay-scrollbar-gtk2

Fix Gtk-Message: Failed to Load Module ‘overlay-scrollbar’

After installing xubuntu-desktop, I've removed some packages that are pre-installed in Ubuntu 14.04 (and no longer required) by this command.

These packages removed successfully and all working fine but some residual config are still exist and hence I removed unity-scrollbar from synaptic residual config:

enter image description here

Which removed files like: /etc/X11/Xsession.d/81overlay-scrollbar.

After logout and login I again tried to launch by command as below:

$ mousepad
$ zenity --info

Now Gtk-Message: Failed to load module "overlay-scrollbar" is gone, and problem solved.
