I have a GL code that runs fine on most workstations, but is somehow corrupted on others.
An image is attached that shows the problem. Once in a while I run into a workstation that
renders all polys in wireframe. It’s as if the glPolygonmode command is being ignored or
wasn’t implemented correctly. I explicitly call glPolygonmode with the GL_FILL flag just before
rendering these objects. The polys are rendered correctly on all machines if the background
image is turned off. But some computers switch to wireframe mode when the image is turned
on. Could this be a driver problem?
