Dark Menu Bar issue with Dual Monitors

Just updated to High Sierra, MBP 13" early 2015 with 2 external Dell P2715Q monitors attached. The menu bar on the second monitor is just a solid blank white line. If I toggle the "Use dark menu bar and Dock" setting off under "General" settings in System Preferences, both monitors display the menu bar icons no problem, however if I toggle the "User dark menu bar and Dock" setting back on, the second monitor goes back to displaying a solid blank white line. I've tried rebooting, same results.

Any ideas?

Thanks!

MacBook Pro with Retina display, macOS High Sierra (10.13), 13" Early 2015 MBP

So this is interesting, I think I just solved the issue. For anybody else out there that may experience the same issue, how I fixed it was to go to System Preferences and select "Displays" and then select "Arrangement" (which will be displayed on your first monitor) then drag and drop the "white bar" that is displayed in the image at the top of the first monitor over to the second monitor and once that is down, drag and drop it back to the original position.

This seems to have fixed it for me, hope it works for you too!

So after a complete erase and fresh install of High Sierra 10.3.1 (released today), I can confirm that:

1. The bug is still present.

2.1. It occurs immediately after you disable System Integrity Protection and toggle Dark dock & menu bar in System Preferences / General.

2.2. Re-enabling SIP, reboots, SMC- or NVRAM-Resets are all useless to fix it after that.

Think the demography of people doing this is very low, that's why this issue isn't widely reported. 😟

I've not disabled SIP so I don't think that's a factor in this. 🙂 The initial boot when dark mode is enabled it seems to work, but after a reboot it happens.

So far the only way round it I found is to disable 'Displays have different spaces' in Mission Control settings, but it ruins my workflow as I run my main application on an external display and use the Mac's screen to flick between spaces for references, IM clients, a Windows VM, emails etc. With it off you flick between spaces on both screens, so can't keep my main app open when I switch!

Exactly same problem, however the solution doesn't work for me unfortunately. Totally bummed.
