photopea has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-ui-3] Showing crisp cursors ==
Today, there is no way a website can provide "crisp" custom CSS cursor. Every browser scales the cursor image up according to devicePixelRatio (just like browsers do with <img> and other elements). 

Here is a demo: http://www.ivank.net/veci/cursors_dpr.html

The cursor center (in "px" units) is interpreted as scaled by devicePixelRatio in some browsers (so even the first example looks different in FF versus Chrome - a different center spot).

My proposal is to interpret cursor images always in hardware-pixel coordinate space. Websites can simply provide larger images, when devicePixelRatio is large.

Other solutions would lead to new CSS parameters and new sources of confusion.
