What do you mean by "glichtes"? Can you attach a screen capture? I don't see anything odd on Ubuntu 19.10.

I can test on Ubuntu 18 and let you know if I see the problem.

Bugbug thinks this bug is a regression, but please revert this change in case of error.

The address bar temporarily enlarge then returns to normal size when click web page.

Okay, after trying again I do see this happen on Ubuntu 19.10 but only with a 50% chance or so.

I suspect this is just different window manager behavior on Gnome compared to Windows and Mac, and there might be no good fix here. Maybe our Gtk widget implementation can suppress the initial focus event when activating the window and focus is about to move somewhere else anyway, or something like that.

Also this is probably not a recent regression, the megabar design likely just makes this more visible.

I could reproduce the problem intermittently. It looks like the address bar gets focus and loses it immediatley, causing an expanding then contracting movement.
what I did usually was CTRL+T, click outside the window, click on content. Doing it repeatedly makes it easier to reproduce.

I can also confirm that the bug affects Firefox 73, the new design just makes it more visible, as Dao said.
