It's related to depth buffer precision.  On my Geforce cards (2MX and
3), it never happens with the 24 bit depth buffer you get by default
at 32bpp.  At 16bpp, it picks a slimmer depth buffer (probably 16 bit)
and the texture layers bleed through.

The code is using a pretty big argument to glPolygonOffset, and I've
never investigated how small it can be.  If someone has a little time
the next time they see this issue, try changing the value of
POFF_UNITS at the top of Cockpit/panel.cxx.  Decrease it until the
textures *just* start to interfere with each other, and post the value
that works for you.
