How reliably can you reproduce the problem?

Comment 2

Do you need to be logged in to see the search box?

I noticed it a couple of times in the last five days, that's why I now created a ticket.

It looks like you need to be logged in to see the search box, yes :(

Even logged in, I don't see the search box. Can you share a bigger screenshot? Anything you can do to figure out reliable steps to reproduce would be valuable.

Were you? I can't log in to the forum. The session of my new account is only valid for their main page. I might be waiting for a cron job.

Unfortunately I can't give STR. But it always happens after a while with WebRender enabled. 

Here's a bigger screenshot:

Another thing I noticed: 
If I take a screenshot with Firefox Screenshots it is displayed correctly. Not if I take the screenshot on the OS level. So the issue seems to happen somewhere in between.

STR: Log in, switch to second tab, reload, wait until everything is loaded, scroll down, zoom in or out, scroll up.
