Dear VMD-L,

I am facing problems with vmd1.8.2. opengl on an IBM Thinkpad laptop.
VMD loads but horizontal lines flicker and make the whole thing messy.
It even renders the proteins but the horizontal broken lines flicker and
it is difficult to do any visualization. I can't describe this better.
Given below is the o/p of glxinfo. Any help is greatly appreciated.

do you need any more info?

vmd console *doesn't* give any error.
