I set small always to 22 and large always to 32, as there're no 48 or 64 icons available at the moment.
On my UWHD (3440x1440@125) they were too small or too large on DO12, that's the reason why I updated the set. But maybe I did something wrong using the new dpi-entries (on my screen the icons are looking good).
BTW it was a good idea not to continue working on the new iconset in the past... as GP mentioned that they now have 4k, I was sure 22/32 pixels will be outdated soon .
