[Paraview] clipped scene with GPU rendering on NVIDIA tesla C1060

[Burlen Loring]

Hi Pratik,

I have had some similar issues when my desktop screen resolution was 
higher than the server display resolution. Do you know what the display 
resolution is set to on the server side? I was able to check the server 
side resolution using xrandr command. The issue was fixed by increasing 
the server display resolution in the xorg.conf. This could be one 
possibility for what you are seeing.
