Video showing the bug

Overview: In the game Insurgency, fire effects (as those from Molotov Cocktail)
create black circles around the fire, creating difficulties to see what is
behind the fire.

I have tried to change graphical settings, and no setting solved this.

Insurgency is a 32-bit game, so it is required to build 32-bit mesa.

Steps to Reproduce:
1) Open the game Insurgency;
2) Choose a server to enter;
3) Play with a class with Molotov Cocktail;
4) Throw Molotov;
5) See the black circles around the fire.

Actual Results: black circles with variable radius appear around the fire,
making it nearly impossible to see behind the fire.

Expected Results: there is a reddish/orange lightning and there are no black or
non transparent circles.
