Looks fine on Mac Version 60.0.3112.0 (Official Build) canary (64-bit) and Mac Version 59.0.3071.61 (Official Build) beta (64-bit).

Could the test team please try to reproduce on one of the listed CrOS devices?

Tested this issue on Chrome OS using chrome version stable # 59.0.3071.91/9460.60.0 by following steps mentioned below.

1.Opened https://jsfiddle.net/wy5pz3wa/ and then resized the window
2.Observed smooth and stable gradient and Not observed uneven gradient, weird color banding and the colors bouncing when resized/Scrolled (Please refer Video)
3.Opened https://auth0.com/learn header  and Scrolled the page with smooth scroll touchpad and did not observe gray gradient artifacts color banding, jitter, etc.	


Note:
As we don't have Veyron_jaq, Cave devices tested this Issue on Falco

Songsuk@ : Could you please help in testing this issue on Veyron_jaq, Cave devices if its available there.

Thanks in advance!

Reproduced this again on cave and others:

Steps to reproduce:

1. open the https://auth0.com/learn web page
2. scroll SLOWLY using two-finger scroll to see jumping gradient colors
3. observe the image with EYES, not by recording internal chrome buffers

see attached vids shot from the phone camera

compared to firefox, auth0/learn: (showing Chrome, then switching to FF, then Chrome, FF, Chrome):

videos are not very crisp since I do not have the right equipment with me but still you can see the color bouncing in chrome
 

Thank you for providing more feedback. Adding requester "schenney@chromium.org" to the cc list and removing "Needs-Feedback" label.

This is only occurring on one device family, suggesting a graphics card issue, or maybe on that device things switch to software rendering and that has the artifacts.

Over to the GPU for further triage, as this issue must be somewhere in the raster pipeline.

This is intended. This is an artifact of the cheaper display panels used on some devices which display at 6bpp instead of 8bpp like higher end panels. Even though we enable dithering, which improves the situation a little, the banding is still visible.

Thank you very much for explanation! 

I would greatly appreciate just in case you could add a short clarification - does ASUS Chromebook Flip C302 fall into this category also (because this is the one I am using and where I noticed this thing)? 

It is a $1200 computer and still comes with a cheaper 6bpp low-end display panel. That is a nice issue to mention in the reviews!

I see the banding on the C302 as well. It's a higher end display, but still 6 bit (notice the line that says "6 bits per primary color channel"):

Overall, the gray gradient used on that website is so narrow that banding is hard to avoid. I even see a little bit of banding on my HP LP3065 which is natively 8 bit...
