I'm using a very recent pull of fgdata with no local mods. The "hat effect" shows up from low angles in all material modes - regional/global/dds. It's most apparent at EGMH, but can also be seen at KSFO. At higher angles or if I zoom in it disappears from the closer trees - but, like you, I can still see it at longer ranges. The angle/range effect would suggest that it's a mipmap thing - perhaps try a bit more space around the trees in the texture? I would give you some screenshots - but that's broken here.
