Problem with reflection of refractive objects

[Bormax]

Hi
Simple scene - wine glass with faceted surface stands on reflective surface of the table. Glass material set as no caustics - Caustics (slow) unticked. In this case reflection of the wine glass is correct if glossiness of the table surface set to 1.0. If glossiness of the table surface set to something lower - 0.99 for example - reflection of the wine glass gets not correct.
If Caustics (slow) is ticked in wine glass material, reflection gets correct with glossiness of the table surface lower than 1.0

Hi,
This is known issue. Possible solution would be to use rayswitch material - glass without custics plugged into global illum slot and glass with caustics plugged into rest of the slots.

Thank you romullus, I’ll use this workaround
