Stair Railings Clipping Through Walls

This doesn't happen with every railing, but with any type past a certain thickness,  the edges clip out through the walls where they intersect with them. This leaves them visible and, while not impeding gameplay at all, it's unsightly, obnoxious, distracting, and I cannot imagine it's an intentional aspect of the game.  

This happens regardless of whether the wall is an interior or exterior wall, and will occur 100% of the time if, as stated above, the railing isn't very thin. Basically, if the mesh of the railing is wider than the thickness of the wall, it will clip out of both sides of the wall/the wall will fail to block the railing from showing up. 

This is admittedly not a high-priority bug in that it doesn't impact my ability to play the game, but since no one else has reported it (as far as I can see), and maybe it's related to other issues that are more severe, it seemed like a good idea to document it. 

Thanks!
