[vtkusers] Issue with automated screenshots of InfoVis graphs

[Timothy C]

Hello,

I am trying to write a program to provide visualisation images of graphs to
be run via remote access. I am currently feeding a graphLayoutView's
renderWindow into a windowToImageFilter.

In my tests on the local machine, the output image is coming out wrong. I've
attached an image file of my output (if attachments work on the mailing
list) because it's hard to describe in words exactly what's going wrong. The
edges of each frame are being filled with garbage data, with the actual
image of each frame squished inside. This same issue occurs live in the main
window while holding down the left mouse button.

This issue only occurs on Graphs - 3d objects run fine.

I am running Ubuntu 11.04 on a Dell Studio 1700-series laptop withan ATI
Mobility Radeon HD 4650 graphics card and OpenGL version 3.3.10665
Compatibility Profile Context in 1600x900 resolution.
