Config and log attached.

Tested again as of v0.19428.
For me it still happens consistently with shadows enabled and not at all when shadows are disabled.
It's the first switch from flight mode to build mode that seems to trigger it.

Andy,
Now that i know what I'm looking for I can see it starts happening the first time I switch from flight mode to build mode (only when shadows are enabled) and it is pretty consistent.
The problem is not only limited to build mode though. I've seen the effect when in flight mode too.

As of v0.19242 I'm still having a ton of problems with the rail docked parts of this ship:

Small update: I think I found out what is triggering the lighting issue.

AndyP,
I just tried a fresh installation and I can still see the standard hull texture issues and beacon issue (though neither quite as severe as the images posted above). The overbright lighting hasn't appeared yet, but that is an intermittent issue so I can't be sure that it won't come back again without more testing.

I'm experiencing the same issues as described above with standard armor and beacons, but none of the others.
