The icons for the heat inserter, as well as the long handed heat inserter, are cropped, but not each one, just the medium size ones?

Hm, that's odd, are you playing with any other mods that are affecting the technology? Playing with vanilla/space age v2.0.55 (latest stable version) and this mod by itself, the icons look fine to me.

I can see that you are running with other mods, since there is Nuclear Science tech in your image. Might be some kind of incompatibility, either a mod that's changing the basic yellow inserter techs, or modifying the heat inserter techs. You can hover over the tech icons to see which mods are affecting them.

I'm playing with plenty of mods, however nobody modified the tech.

Tried with no mods (even space age), only heat inserter and its dependency, and still, even in a new game, the icons are still cropped.

My testing was made with the map editor tool.

Hm, that's odd.. I wonder if it might be a resolution scaling issue, perhaps? I haven't really tested alternative resolutions, but I play at 1440p, borderless windowed, with 125% UI scaling.

Ahh, if I drop into windowed mode and reduce the size of the window so that the automatic UI scaling is at 75%, the icon does appear bugged. I'll try to look into it

Figured it out, somehow I messed up when creating the tech icons in the first place, in a way that's only noticeable at non-default resolution scaling. Should be fixed in v1.1.8

Nice B)
