Flickering and bright lights on global illumination

With the last patch I started to encounter a problem with static Lights with global illumination turned on. After some playtime they become extremely bright and flicker. For example in town the whole town was in a bright red light, because someone used an MTX shield with a red glow effect.

here is a screenshot of torches in the temple of decay being extremly bright.

the problem also happens to me on the vulcan renderer.

on GI ultra setting the flickering disappears but the brightness persists.
