I rechecked this problem, seems feedy(or infoq?) fixed it.

I tried at another notebook with a GPU freq = 0.9 GHz, and Chrome M51. I
cannot reproduce this problem any more. But at this machine, i found
another similar problem: a sentence is wrapped in a <b> element, surrounded
by normal text. It took ~1a delay to display, from blank.

So i guess it's partly alleviated by feedly's update or OS update?
(Recently Windows 10 on this 0.9GHz notebook has updated to latest)

I remember having seeing ~3s delay whenever the popuped RSS article
contains italic text. But now it goes away.

So i tried again on another notebook with M54(4.0.2840.71 m (64-bit))
Chrome and lastest Windows 10. After opening several articles on feedly, I
observed a similar scenario: the chinese italic text is embedded in an <em>
element, and user agent stylesheet has set em element's default style to
italic. The chinese italic text took a delay to display, but the delay is
now <1s, but can be perceived. The article's url is:
http://36kr.com/p/5060348.html?ktm_source=feed , and this notebook's CPU is
2-core i5m 2.67GHz.

You need a feedly account and subscribe 36kr's RSS in feedly. The url is copied out from feedly.

Months ago i observed ~3s delay for displaying italic fonts between the normal text. And days ago i still observed <1s delay(not obviously but perceivable)

Also i used to see the delay on a low-performance notebook which has only a intel ATOM cpu with no SSD drive. (At that time, when problems occur, i have no way to access google networks due to gfw, so unable to report it)

I'm glad to say this bug is not annoying me now, so i'm only submitting it here for logging purpose.

As chrome-hyd team do not have 'notebook' to triage the issue ,Could anyone from MTV team please look into this issue.
Thank you!!
I recently re-experienced this problem on Dell Inspiron 17 - 7737, a notebook with i7 cpu.

The point is, the italic chinese characters in <em> take a little delay to display with other normal text.

Also, if the hybrid “ <em>中文内容...</em> 正常文本... ”content is displayed from a  static html loading, then no problem.

Perhaps this happens when the hybrid “ <em>中文内容...</em> 正常文本... ”content are dynamically inserted by js? I'm not sure, since https://feedly.com is really a very complex and huge front-end web page...
