Hologram effect broken on track select screen

[JayFoxRox]

The green track in the menu is supposed to flicker and have more patterns to it. However, in the current revision of OpenSWE1R it's static and has a fixed color:

I think I also had cases where this did magically work at random points during an OpenSWE1R session.
However, this is speculation and I'm not sure if I remember correctly.

To me, this feels like uninitialized memory or bad default renderstates. Maybe the vertex color is not respected properly.
This might also be a regression, so it needs further testing.
