I have just installed netgen on the ubuntu 12.04 LTS. Everything seems fine, except that the structure/geometry in the workspace is not being displayed properly. It seems to be "semi-transparent" and show what is behind the window instead (like there is a hole in the GUI). You can view the structure/geometry if you move it. So the workaround I have now is to slowly, but constantly, move the geometry so that I can see it. However, this is annoying, and any help would be very much appreciated.
