[Paraview] Machine hangs when using Paraview

[wang]

Dear Paraview Users,

I experience probelm with Paraview after the Fedora operation system is 
installed. Whenever opacity is reduce from 1.0 the machine hangs. The 
only way to step over is to reboot the machine. Reboot doesn't always 
OK. Sometimes it took a while before the monitor can show something. 
Paraview versions 3.8 and 3.10 make no difference. Also Fedora13 and 14 
makes no difference.

Does anybody else have the same problem? I'm keen on hearing your 
experience.

Thanks!
