Происходит потому что emissive текстуры в текущей реализации рендера не прозрачные.
В данном случае можно обойти эту ситуацию, положив лампочки внутрь а у самой текстуры выключить свечение.
Однако остаётся вопрос, есть ли ещё такие поверхности? возможно где-то всё же понадобится честная реализация прозрачной светящейся текстуры.

I thought of checking it out in GL renderer, and surprisingly, the texture is completely different...

@MaxG2D because RenderMode is Color.

У нас rendermode 1 (color) просто применяет на текстуру цвет из rendercolor и полупрозрачность из renderamt.

В то же время в GL всё тоже самое только браш теряет текстуру и работает с чистым цветом.
