[YaST] Bug in scrolling while moving the mouse

Hi,
I'm testing the openSUSE 13.2 Beta with KDE on a 64 bit system. I've noticed a strange behavior in text components of YaST modules (K Menu -> Computer -> YaST -> Release Notes or from the desktop "Install" shortcut). If you try to scroll while moving the mouse automatically the scroll bar restart from the beginning.

Do i have to file a bug? If so, in bugzilla i've to file it for openSUSE Factory, right?

Bye

[UPDATE] I've noticed same behavior with every component of YaST that uses the scrollbar: list boxes, text boxes...
