Thanks for the reply Peter.  On the PC that's broken, I'm running KUbuntu
in a virtual machine (virtualbox).

I just disabled 3d acceleration on the guest os, and now it work!  Though I
do get the following error:

OpenGL Warning: Failed to connect to host. Make sure 3D acceleration is
enabled for this VM.

It uses OpenGL (for 2D acceleration), rendered inside a GtkGLExt widget. It=

<br>
Do you have any issues with other 3D software, or just PCB? What is your gr=
aphics card, distro and currently installed driver?<br>

I had a machine here at work today which displayed PCB&#39;s viewport compl=
