linux release V10 10.4.9 18980 beta - display problems

I have installed the up mentioned BricsCAD version to my Opensuse 11.2 KDE4 with display adaptor ATI HD 2400 Pro and video driver ATI Catalyst 10.5 (2D version 8.73.3, RandR version 1.3, OpenGL ATI 3.39836 Compatibility Profile Context).

I encounter a sum of problems for display:

-tremulous and instable image during editing/drafting commands

-dirty display during drafting

Can someone help me to solve this problem it is only a question to better configure ATI driver? or it is a bug of BricsCAD?
