Same issue with the stable FF43?

No. I think the bug was introduced about four days ago in Nightly.

Do you have a demo to test?

I tried this demo of simple push: https://simple-push-demo.appspot.com/
WFM, the push notification is displayed at bottom right with Nightly (1080p screen, resolution 125%).

The screenshot shows the bug occurring in the demo.

And if you go back to 100%, same issue? (to know if it's related to 4K screen or not)

Yeah, was just trying that now. After setting my resolution to 1080p and 100%, the bug didn't occur. Also doesn't occur if I set my resolution to 4K but keep the DPI at 100%.

As you have a 4K screen to test, it would be useful to find a regression range in Nightly.
There is the tool Mozregression for that, see http://mozilla.github.io/mozregression/ for details.
You just need to install python 2.7 and the package mozregression (the command-line version).

After that, you can run the command "mozregression --good=2016-01-01" and make your test about the push notification.
At the end, just copy here the pushlog provided in the console output.

I can reproduce the notification position problem.

Regressed by: Bug 890156

This bug also be affected bot only the push notifications but also Notifications API[1].

Looks like a dup of bug 1240085.
