[Paraview] vtkXOpenGLRenderWindow Error

[Magician]

Hi all,


I've been trying to solve the problem.
I found an important setting about it.

Our ParaView is running on shared Linux cluster,
so we operate ParaView with VNC Client.
My VNC setting is very simple as below:
> vncviewer -geometry [width]x[height]
But other users' settings are little different:
> vncviewer -geometry [width]x[height] -depth 32

The -depth option is critical.
Maybe this option influences OpenGL setting of VNC,
and ParaView gets into GLX errors.
I suggested removing -depth option and restarting VNC server,
then our ParaView executed perfectly.
