This workaround “fixes” the issue:
- Open one thread with a lot of posts
- scroll a few pages down
- refresh browser window
Afterwards, the title header behavior seems normal for this browser window session.

almost… only funny thing is when you return to the main page, you then have two title bars until you scroll down a little 
clearly the discord developers made a boo boo. We can’t be the only ones, I’m sure there will be a patch soon
I think this is a problem with the discourse theme or color scheme being used on the openHAB server because my server doesn’t have this issue. In openHAB the top nav bar is transparent and there is no icon. My server runs discourse 3.4.0.beta2-dev
Yes there seems to be some custom CSS added to the Discourse themes to tweak the default Discourse header bar. It probably was added to prevent two openHAB logos from showing when the custom navigation bar at the top of the page also shows.
You can see this CSS while using the Developer tools and also disable it to undo these tweaks:
Without these tweaks it will show the two logos again though

So it is only an issue in the openHAB Discourse instance because of this configuration.

I figured it was something unique to openHAB’s setup because I don’t have this problem on my server.
On my site I use the Brand Header theme component addon which is maintained by the discourse team to add buttons on the header to lead to other pages on the site. It works well and looks similar to what we have here
