[FR] Stained glass Tomarani spandrel is broken when on inside walls

The glass in the spandrel from For Rent has shading issues when placed inside closed rooms. 

The wooden part seems to react somewhat properly to light, but the glass part glass turns weirdly yellow no matter how well the room is lit. (the rooms in the photo all use the same swatch!) This happens to all swatches but is mostly visible on the blue glass ones.

The issue persists in live mode and after restarting the game.
