Linux Mint 21.2 Beta Cinnamon ISO or NixOS unstable, both should have mint-y-icons 1.6.6 and cinnamon 5.8.2.
The observation is, when using Mint-Y-* as icon theme and opening cinnamon-settings, I found the icon for 'Gestures' "has different border radius compared to other icons":

I imagine that icons added in https://github.com/linuxmint/cinnamon/tree/5.8.2/data/icons are mostly matching the style of Mint-X, and looking in https://github.com/linuxmint/mint-y-icons/tree/master/src/categories I cannot find a corresponding icon for Mint-Y.
I unfortunately don't aware of good candidate in moka-icon-theme, thus I am filing the issue :-)
