+DESCRIPTION OF PROBLEM:
+=======================
+
+The example map, maps/sparkly_seam.map, contains two triangular brushes near
+the side of the room.  The seam between these two brushes "sparkles" even
+though the endpoints of the edges are exactly the same.
+
+To trigger the bug, compile the map; you don't need -vis or -light.  Only
+-bsp (the first q3map2 stage) is necessary to trigger the bug.  The only
+entities in the map are a light and a info_player_deathmatch, so the map will
+compile for any Q3 mod.
+
+
+SOLUTION TO PROBLEM:
+====================
+
+None yet.  The problem is likely caused by sloppy math operations (significant
+loss of precision).  This bug pops in and out of existence with every other
+commit at the moment.  The problem is likely caused by the operations in the
+brush winding computation (where the planes are intersected with each other).
+I have not gotten around to addressing that code yet.
