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

You have three options here:

  • Ignore the warnings

  • Remove overlay-scrollbar stuff

    #Step 1
echo "export GTK_OVERLAY_SCROLLING=0" >> ~/.profile

#Step 2
mkdir -p ~/.config/gtk-3.0
cat <<EOF > ~/.config/gtk-3.0/gtk.css
/* Adding the buttons on the edges (if you don't need them, skip the next 4 lines)
 */

.scrollbar {
  -GtkScrollbar-has-backward-stepper: 1;
  -GtkScrollbar-has-forward-stepper: 1;
}

/* Scrollbar trough squeezes when cursor hovers over it. Disabling that
 */

.scrollbar.vertical:hover:dir(ltr),
.scrollbar.vertical.dragging:dir(ltr) {
    margin-left: 0px;
}

.scrollbar.vertical:hover:dir(rtl),
.scrollbar.vertical.dragging:dir(rtl) {
    margin-right: 0px;
}

.scrollbar.horizontal:hover,
.scrollbar.horizontal.dragging,
.scrollbar.horizontal.slider:hover,
.scrollbar.horizontal.slider.dragging {
    margin-top: 0px;
}

/* Slider widens to fill the scrollbar when cursor hovers over it. Making it permanent
 */

.scrollbar.slider.vertical:dir(ltr):not(:hover):not(.dragging) {
    margin-left: 0px;
}

.scrollbar.slider.vertical:dir(rtl):not(:hover):not(.dragging) {
    margin-right: 0px;
}

.scrollbar.slider.horizontal:not(:hover):not(.dragging) {
    margin-top: 0px;
}

EOF

#Step 3
cat <<EOF > ~/.config/gtk-3.0/settings.ini
[Settings]
gtk-color-scheme="tooltip_bg_color:#ffffaf\ntooltip_fg_color:#000000"
gtk-application-prefer-dark-theme=0

gtk-primary-button-warps-slider = false

EOF

#Step 4
sudo apt-get purge overlay-scrollbar overlay-scrollbar-gtk2

  • Reinstall overlay-scrollbar stuff

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

  • I tried to reinstall overlay-scrollbar, but terminal said: E: Unable to locate package overlay-scrollbar-gtk2 Then to remove overlay-scrollbar stuff with your steps. And now the errors come again without first line Gtk-Message: Failed to load module "overlay-scrollbar – zSakhalin Dec 09 '17 at 14:46
  • Do you read my answer correctly? I present three variants (logical "OR"). – N0rbert Dec 09 '17 at 14:48
  • Yep. And I tried all of them (exception is first) – zSakhalin Dec 09 '17 at 14:51

on 64bit LTS18.04, overlay-scrollbar-gtk2 did not get rid of the gtk-message Failed to load module "overlay-scrollbar while overlay-scrollbar-gtk2:i386 did the job, that is:

sudo apt-get install --reinstall overlay-scrollbar overlay-scrollbar-gtk2:i386
