[Bug 86816] rendering artifacts with WebGL zombies

--- Comment #14 from Jakub Szuppe <jakub+mesa at streamcomputing.eu> ---
Variable add is uninitialized before operation add += color = org = texture2D(
map, uv ); (line 266 in webgl_zombies.html). Initializing add or changing that
line to add = color = org = texture2D( map, uv ); fixes the problem.

(Setting glsl_zero_init=true before starting browser also fixes the problem.)

Kind regards,
