Does this occur on other versions of Chrome (that is, is this a regression)?

Could you please provide about:gpu in your configuration with GPU acceleration disabled?

Why are you running Chrome in this mode?

>Does this occur on other versions of Chrome (that is, is this a regression)?

This has been worked with GPU acceleration enabled, so probably no.

>Why are you running Chrome in this mode?

I'm trying running browser tests on Travis CI (with its Docker service to run Xenial) and it doesn't provide GPU acceleration capability.

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

Please provide the contents of about:gpu (plaintext copy/paste is fine) from the system where you're running Chrome in this configuration.

I cannot plaintext copy/paste from Travis CI as it does not provide GUI. Is there a way to access it in CLI?

I confirmed locally that running Chrome on Windows with --disable-gpu reproduces the problem. SwiftShader renders this sample differently than the GPU. Nicolas, could you or Alexis please diagnose this?

Thanks for reporting this. I'm able to reproduce it, and will have a closer look.
