Performance issue with new symbology

I have some performance issues with the new generation symbology. Using a polygon layer  with a categorized symbology . Up to a scale to approx. 1:200 there are no issues and rendering is as fast as with the old symbology. But between approx. 1:200 - 1:1 it slows down and eating 100 % CPU for half a minute sometimes even longer. This does happen on several (RedHat?, Ubuntu) Linux systems with different QT versions. On a Windows XP machine with OSGEO4W install there are no performance issue (but it fills the polygons black sometimes when zoomed in).
