This is exactly the taskbar thumbnail effect where I asked you to not 
use it because it is not suited for anything except uasge in the taskbar 
thumbnails. If you use lxr.kde.org you will see that it is used in 
exactly two places: the tooltip content for the normal tasks applet and 
the one for icon tasks.

Of course it is questionable that it is public API. But the knowledge 
that the effect is unsuited for anything else than taskbar thumbnails is 
rather new (we discovered with window strip in Plasma Active).
