I have try to reproduce this problem on my Solaris 10 x86 CDE and JDS. But I can't reproduce it. Reproduce video attached. 

Attached is a 7 zip compressed format. I can't use zip format since the compressed format will be much bigger. You can download 7 zip here: http://www.7-zip.org/ I don't know whether 7 zip works fine on Unix systems. Sorry.

The video is AVI format. I recorded the video on Windows, since I have a Solaris installed on Vmware.
