The transparent materials appear weird in Arctic mode. There seems to be a non-linear transparency level transition that does not reflect the actual numbers in the “Trans” slider ranging from 0 to 100%. While in Arctic mode, the transparent materials are almost non-transparent until they reach 39% from the slider where they appear as 3-5% transparent, then moving the slider to 40% suddenly changes the transparency into something that look more like 95-97%. There is no such issue in the rest display modes. Is it possible to fix that apparent bug for Rhino 7?
