Why does Photoshop poorly rasterize text in linked Smart Objects?

Question

Design

I insert the associated smart object into the document, and in it all the text is rasterized bolder / denser. See for yourself: This is how the Closer
menu looks like . The pixel relief does not change. That is, it's not the smoothing method (clear, saturated, etc.). An associated smart object is an external psd that is thrown into the document by a smart object. When editing an external psd, Photoshop itself checks it, rasterizes it and adds a new version to all open documents. "About the system" from Photoshop UPD. The same thing happens with text if you open psd, until you try to edit it. Fira Sans font.

Answer 1

For starters, you need to slightly increase the font size. Not a single letter falls into the pixel grid in height, the contours are anti-aliased.
By subject - you need to look at the layout. Maybe there's something wrong with the blending modes. Attach the source ...
But I can reassure you in advance that both options ("as it should" and "as it turns out") are ultimately meaningless, since the browser will render the text in its own way, and not the way Photoshop does. In the browser, the text is much uglier.
PS: for me, "how it turns out" looks better.
