Which wiki?

We have fixed that problem in the gadget before on enwiki but different versions can exist on different sites.

English and French Wikipedias.

I'm not seeing in Chrome on en.wiki. When Live Update updates, the hover preview changes to a preview of the new link that is under my cursor, which is as expected. When I move the cursor away from any links, the popups disappear.

I couldn't reproduce it either. But, i wouldn't be surprised if there are some timing issues / race conditions. I don't think any one of us really understands how this code works/behaves, so :)

I just watched @Trizek-WMF reproduce this without live update enabled. It's intermittent but happens maybe one out of every 4-5 times he hovers from one link to the next. I'm pretty sure this is a bug in NavPopups, not related to RecentChanges.

I can confirm that it is happening (intermittently) on other pages too. I've just experienced this hovering effect while reading an article. Since, I can't reproduce it. Therefore, there is a bigger probability of a bug from the Pop-Ups than from RCs.

I've been getting this for some time on Firefox. Yeah, the logic for positioning the popups and divs is... a bit weird, even by Navigation Popups standards. Nevertheless I think there's some relatively low-hanging fruit with regards to mouse detection, so I'll do some more experimentation with that and see if we can fix it.
