Description Bastien Nocera 2014-04-13 15:30:21 UTC 
Might be a GTK+ bug.

Search for "Sablons", and scroll in the results using the mouse wheel or 2 fingers on the touchpad, you'll get bits of selected background (blue) show up in the list and not get updated.

Yeah, whats up with that?

I'll see if I can come up with a stand-alone reproducer to see if it's a GTK+ bug (or if someone else wants to have a go at it, please go ahead).

If someone knows a GTK+ hacker with loads of free time (like those exists) pointing them towards this would be nice.

The bug looks somewhat like this and this happens on scrolling the list with mouse cursor on top of it.

it may be solved by setting 
       <property name="hover-selection">False</property>
but then it loses focus(doesn't show the row you are on as a blue highlighted) on what list row you are on.

I experimented further with the above property set to False, and used a css class that would give same result on hover 

.search-list GtkTreeView:hover {
    background: #3465A4;
    color: #ffffff;
}

and still the list is not getting updated, blue colors like in image still remain.

So I guess this is a problem with "hover-selection" of GtkTreeView while scrolling, not just a maps problem.

I might be wrong, and there might be a workaround for that which I missed.

Managed to reproduce it with simple c program, filed bug in Gtk+ as bug #728284
Comment 4 Mattias Bengtsson 2014-06-11 23:50:57 UTC 
This is fixed as of some recent Gtk+ release. Closing.
