As pictured, Maliwan sniper rifles are missing their glowing elemental bits after the UHD update. It appears all elements are affected. All other Maliwan weapon types appear unnaffected.
I did notice that accessory elemental items like the three shock canisters on the side of the rifle barrel for shock elemental snipers DID have their glowing texture and DID flicker when reloading. I may be wrong about this, but it also seems like the glowing effects on the other weapon types are less vibrant than pre-patch. I believe they had a sprite/particle glow effect in addition to the texture?
