Windows Taskbar Icons Have Ugly Border

Nowadays, icons really look good due to vector graphics. However, I somehow have the impression that something must have gone wrong, since the Google Chrome shortcut icons of Google Maps/Search and Craft look a bit odd, like the rendering did not work properly at the circled border (especially compared to the other icons).

Is there maybe an easy way to fix this?

Inspired by Daniel B, I did an easy workaround which is not perfect, but good enough for now. I converted the .ico into a .png file using online converter, and then back to .ico. The end result is a rectangular icon with solid background (since the transparency got lost during conversion).
