Tested the issue in Android and able to reproduce the issue. 

Steps Followed:
1. Launch Chrome.
2. Navigate to chrome://version
3. Observe weird font

Chrome versions tested:
67.0.3388.0(Canary)

OS:
Android 8.1.0

Android Devices:
Pixel XL

Using the per-revision bisect providing the bisect results,
Good Build - 67.0.3387.0
Bad Build - 67.0.3388.0

You are looking for a change made after 547606(GOOD), but before 547607(BAD).

CHANGELOG URL:
The script might not always return single CL as suspect as some perf builds might get missing due to failure.
https://chromium.googlesource.com/chromium/src/+/aa8304925672de76f13fcd46d49f305d98e636b6

From the CL above, assigning the issue to the owner concerned.

@cnardi: Could you please look into the issue, pardon me if it has nothing to do with your changes and if possible please assign it to owner concerned.

Please navigate to below link for log's and video--
go/chrome-androidlogs/829163

Thanks!!

Fairly confident this isn't my change, all it did was change serialization via Javascript which should have no effect on rendering.

Nothing strange jumped out at me from the changelog, perhaps this was actually a painting/compositing change? Maybe a re-bisect would help?

This could be a canary only variation which is why it did not appear in Dev 3387. Can you rerun with wider range (verify ranges) and Finch params in #1

Still happening on 67.0.3390.1 (Official Build) canary (32-bit)

Retried the tool bisect with different range, still didn't get the possible suspect. (Able to get the good and bad combination in tool bisect)

Unable to find the exact suspect from manual change log as well

CL: https://chromium.googlesource.com/chromium/src/+log/67.0.3387.0..67.0.3388.0?pretty=fuller&n=10000

Requesting someone from Blink>Fonts team to take a look at this and help us in assigning the issue to appropriate owner.

Thanks!!

Since this is a recent regression, tagging as RBS.

This is no longer happening on my canary chrome android 67.0.3396.3

Is this now fixed? Please update the status of this blocker as soon as possible.

I don't think this is a dup of 840010 and associated issues, which were a regression introduced late last week and now reverted.  It does seem like this may be fixed now, however, please reopen if experiencing again.

Thanks, hcm@, sorry if I shoved this in the wrong triage bucket.
