[Paraview] parallel rendering problem

[Berk Geveci]

The problem is that the server windows are overlapping. Most OpenGL
drivers, specially on Linux, does not fully render in regions that are
obscured by other windows. There are a few ways to fix this:
0. Make sure the windows do not overlap
1. Do not use parallel rendering - disable remote rendering in your settings
2. Use software rendering by compiling against Mesa

Which one is the best depends on what you are trying to do. It sounds
like you are running the server on the same machine as the client. In
that case, (1) may be the better option as long as you are not volume
rendering. If you are running on a cluster, (0) is the best option.
You can achieve that by setting the DISPLAY properly to make sure that
each window is rendering on a separate display. (2) is the fallback
option but is probably the slowest unless you have a lot of nodes.
