Problems with Anjuta 1.2.3

I've tried Anjuta 1.2.3 on a Suse x86_64 installation, but the editor isn't working. It overlaps lines and positions them incorrectly during scrolling. Now I've downloaded Anjuta 1.2.4 as source code, built it as 64 bit application, and the editor is working correcly in this version. Has anyone an idea what is wrong with the 1.2.3 version of Suse?
