tool bar icons is just svg without opacity, smoothing or other filters... And I don't see blurring on this screenshot...

Zoomed in to highlight the problem: I suppose this might be that the icons do not properly align to the pixel grid which causes even straight lines to appear blurred with the background. Below are icons as they should be rendered.

Here's also Figma's toolbar, zoomed in, look at Rectangle, Frame and Text icons specifically:
