The normal cursor's point isn't at mouse's coordinates. It seems to be a few pixels too high and a bit to the left. See attached screenshot:

In the picture I have changed settings from Universal Access --> Zoom:
It seems that other cursor types have similar issues as well.
Using Ubuntu 19.04 with the Yaru theme that came with it.
In the mean time I've switched to Hackneyed cursor theme (https://gitlab.com/Enthymeme/hackneyed-x11-cursors) as it seems to be better aligned. Here's for a comparison what the position probably should look like:

Indeed, if one puts the mouse pointer all the way to the screen’s left edge, one can notice the missing border.
I wish the cursor could be sharpened more.
I can confirm that this is still an issue. I was investigating a mouse cursor intersection issue in another application. After a lot of debugging, I found that the Yaru mouse pointer was a couple of pixel two low relative to the visible tip of the cursor image. The Adwaita cursor which is similar in appearance does not have this problem.
I think I know how to fix this 👍
Isn't this fixed? @madsrh @ubuntujaggers ?
