You didn't miss anything.
I dug some more into this, and I have a new STR to reproduce it reliably on my system.

New STR (tested on 62.0.3171.0 Canary):
#----------------------------------------

1) Open a fresh profile (from the "add person" menu).
2) Enter to cnn.com, wait for it to fully load.
3) Tab opening/closing is smooth.
4) Install the "Blue Space Sunset Chrome Theme" theme:
https://chrome.google.com/webstore/detail/blue-space-sunset-chrome/nndfdjfoclbidmgpmbelcieibgjjfdog
5) Tab opening/closing is smooth.
6) Enter to Settings and change the "Manage on startup pages" so Chrome start with the last opened tabs.
7) Close Chrome with the cnn.com tab present.
8) Open Chrome again and wait for it to fully load cnn.com.
9) Tab opening/closing is *janky* when the tab strip rescales.
10) Enter to Settings and change the "Manage on startup pages" so Chrome start with a new tab page (default behaviour).
11) Tab opening/closing is smooth with or without browsing firstly to cnn.com 

Note: Seems like it is affecting only 1 of my machines at home, but not the second one.
Note2: When trying to reproduce these new steps on Chrome stable (Version 60.0.3112.78), I couldn't reproduce the issue.
Note3: Attaching my about:gpu page from the Canary version.

Tested the issue on windows 10 & 7 using chrome M62 #62.0.3173.2 and followed the steps mentioned in comment #3 and still not able to reproduce the issue.

@MTV Team-- Could someone from MTV team look into this as it might be specific to the gpu driver (ANGLE (NVIDIA GeForce GTX 660 Ti Direct3D11 vs_5_0 ps_5_0)), which inhouse team doesn't have.

Thanks!

hdodda: It's been three weeks without a response from the MTV team.  Can you please assign to somebody directly to try to repro this bug?

Still experiencing this issue, which really drives me off of using Chrome.
Tell me if you need any more info to help you reproduce the issue.

Archiving old bugs that have only received trivial updates for some time.

If you feel this issue should still be addressed, feel free to reopen it or to file a new issue. Thanks!

The bug can be closed - I no longer see the janky behavior with the latest Chrome Stable.
