Yes. That's the problem. e.g. you put the mouse on the first visible 
Icon, and you get the hint of the first Icon of the original window 
(before scrolling)

Yes. Should we open a bugtracker issue?

I know that Qt in itself provides a Qt_Listview, which should emulate 
Windows listview, but I don't know to what extent it's currently exploited.

I'm among them. Not only more attractive, but also significantly less buggy.

Currently I'm trying to put some order in canvas drawing, because it 
would appear that each function and each widgetset has its own ideas of 
what the painting rectangle should be :-( , creating a mess if you want 
to have an ellipse inscribed in a rectangle, a pie slice into an 
ellipse, etc. and, in the process I'm trying to see if we may get a 
decent antialiasing for shapes and not only for fonts.

As soon as I'll have some time I'll give a look to the ListView 
implementation in Gtk2 and Qt, if nobody else is willing to do it.

In the meantime, did you give a look to my implementation of the graph 
It doesn't exploit ListView, but it provides the same final result. It 
only lacks a better arrangement of Icons, but it's a rather trivial 
matter (after creating all of them, find the maximum width, then use 
this value to arrange them neatly). It might be a way to get more 
quickly a result, unless you want to take this occasion to try and fix
