In Rhino 8 there’s different svg files for dark mode and for light mode.
The dark mode icons for those two have been generated with an automatic system, that all dark mode icons went trough. That’s why the result might differ, the code interpreted those shapes differently.
Some dark mode icons didn’t turn out so great after the automatic process so they had to be fixed manually. Usually to get the best result in dark mode, is just to manually make different icons for dark and light mode, the automatic systems usually only get about 80% right.
