I think this is my cup of tea...
Can you share your scene, Antoine?

My first guess is insufficient caustic samples.

Also remember that caustics quality ('Lumière résiduelle') can be set much higher than 10 by manually dialling in a number. I've tested with values up to 500. Try a value of 100 and see if your image gets better.

As well as increasing samples on materials individually as well as in the settings panel.
