I agree, transparency may be an issue. Or perhaps the use of  
transparency to implement mouse-over events and non-rectangular shape.

The MATE file manager icons and Gtk+ checkboxes react to the  
mouse-over and they have visual problems. The LXDE filemanager icons  
don't react to the mouse and they look fine.

The icons and the checkboxes are non-rectangular. The checkboxes have  
rounded corners. I haven't seen visual problems with other Gtk+ widgets.
