这个问题在使用不同浏览器的情况下，已持续出现1到2天，且仅在打开论坛（包括此论坛、我的论坛以及其他Discourse论坛）时发生，但在浏览各个主题时则不会出现。
这是有意为之的改动吗？
I can repro on Meta and Try. I don’t believe this is intentionally, but it’s also incredibly minor.
Certainly, in fact I opened this topic only for curiosity, believing that it was a desired change and wondering if I got lost some discussion about it.
If there was discussion I missed it too 
.
The closest thing to a discussion about this that might be related that I can remember seeing was about the importance of having a good title for SEO purposes.
“Page 1” is an awful title for SEO purposes.
It makes sense - text-only viewers / JS disabled users / crawlers get a paginated view of the forum rendered server side so that it can still be used. ‘Page 1 - Discourse Meta’
Then when the app loads the page title is replaced with just e.g. ‘Discourse Meta’.
Maybe you just now noticed it and it’s like the Fedex arrow - you can’t unsee it? 
EDIT: it does appear to be a difference that has come up recently, but I’m not sure why - haven’t dug into it.
Can you repro this @techapj on a connection from India with more delay? I wonder where that title text would be coming from.
It’s coming from the HTML title provided in the initial page load.
Hmm if it is the non-crawler HTML we should fix that @techapj. I can’t easily view source on my iPad to verify.
I can repro this here on Meta, added on my list to fix. 
I just fixed this, the flashing was bugging me.
