Compositor: Uncontrollable glare and noise artifacts In the compositor, I often have an uncontrollable glare I don't know how to get rid of. Usually, tweaking the threshold fixes the problem, but not with those noisy artifacts. Here is my basic setting:

I have noticed that the material provoking this is often (maybe always?) some kind of metal. How do you use metal and glare without have this kind of glitch?
Thanks for your time!

A lot of time wasted on this... but now I know. Thanks Allen and susu for your input!
