Issue descriptionUserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_1) AppleWebKit/602.2.14 (KHTML, like Gecko) Version/10.0.1 Safari/602.2.14 Steps to reproduce the problem: When using a script to change the font size on "window resize" event, and then resizing the window's height frequently, you'll see the memory usage of "Google Chrome Helper" process rapidly increases. From 150MB to around 400MB. See this example: https://jsfiddle.net/cb254p8m/1/ (Please only resize the height, since the font size depends on the height) Even if I use a CSS constant, for example, "5vmin", and don't use the "onresize" event, this issue still exists, see: https://jsfiddle.net/cb254p8m/3/ What is the expected behavior? Like in all other browsers, the memory usage should not rapidly increase. What went wrong? The memory usage rapidly increases. Did this work before? N/A Chrome version: 54 Channel: stable OS Version: OS X 10.12.1 Flash Version:

Please use macOS's Activity Monitor instead of Chrome's internal tool. The process is "Google Chrome Helper".

Still "Unconfirmed"? Yes the Chrome's internal monitor doesn't show this. But you can reproduce it using macOS's Activity Monitor.

I've just found why you can't reproduce it. This is because your Chrome's default font is maybe a Latin font. When I use a Latin font I also can't reproduce. My macOS and Chrome are both in Simplified Chinese so the default font is "黑体-简" (its formal English name is STHeiti). I guess this font is in all macOS versions so I've created a new fiddle for you to test: https://jsfiddle.net/cb254p8m/4/ Good news is that I found in Chrome 57.0.2974.0 this issue disappeared! But in the stable version 55 it still exists. So please test that on v55.

Some Asian fonts have this issue, while some don't. When I research them in macOS's Font Book, it seems only "TrueType" asian fonts (but not "OpenType TrueType" asian fonts) have this issue.

I guess why Chinese fonts can trigger this problem is because their font files are huge.

I found when testing, if it slides very smoothly (I mean at 60 fps), then this font doesn't have this issue. But when it's only 30 fps or less, then most probably it has.
