When I connect my HDMI along with my second monitor and built in display, I get this from my top bar, a weird two-row duplication.

How do I get rid of it?

    Maybe it can help understanding the problem, if you tell us about the graphics card/chip (brand name and model) and the graphics driver that is running. – sudodus Mar 17 '19 at 18:35
  • Is this also happening in FireFox/Chromium or only Chrome? and what's the output to lspci -nnk | grep -iA2 vga? – Fabby Mar 20 '19 at 17:34

  • @Mookey Submit a bug report. This is likely a bug in how HiDPI handling is done, and something GNOME developers + Ubuntu developers should know about and fix. – Sergiy Kolodyazhnyy Mar 24 '19 at 9:29

It's in fact a weird problem. And maybe you should try to open a bug ticket to the Ubuntu Developers. Despite that, this what I would try:

I've solve many issues regarding Ubuntu using Gnome's Shell Extensions, this is one you should try:

Monitors Add-On

If that doesn't work, you might consider upgrade your version to 18.10.

Good luck.
