The work in  issue 713891  to move all layout tests to --enable-color-correct-rendering is essentially done. I've been running Canary with this flag for over a month with no issues. Time to start turning this on to a larger population.

The following revision refers to this bug:

commit 708f986f71d8059c05c0f05b37d8c798a877ffde
Author: ccameron <>
Date: Sat Jun 17 01:29:37 2017

color: Use base::Feature to control color correct rendering

Add an explicit enable command line flag in
ShellMainDelegate::BasicStartupComplete to enable this feature
for layout tests, because it is already enabled for layout tests.

Comment 16 by, Jun 19 2017

This feature is now on for all Layout tests. A few tests periodically time out, but it's not clear (yet) if that is particular to the color correct rendering flag.

The gpu pixel tests will need to be rebaselined for this feature, too, so I have a sub-bug for that ( issue 734255 ).

Several browser and content_browser tests fail with this feature enabled (afaik mostly because they pick up the display color profile), so I have a sub-bug for that as well ( issue 734262 ).

Once I have all tests switched over, I will try just flipping the switch (which is 1 line because of the change in #15). I suspect that I will have to turn it off due to rasterization performance regressions (for which I've already filed issue 719735), but I hope to leave it on long enough to flush out any surprises.

Comment 20 by, Jun 28 2017

I'm planning to enable this feature by default now.

Layout tests, GPU tests, and content_browsertests, and browser_tests area all running with this flag, so there should be minimal movement on the waterfall.

That said, this touches basically everything, so I do expect some surprises.

Sorry, I think I spoke too soon. This DOESN'T look like it's fixed in 62.0.3169.0 (Official Build) canary (64-bit). I'm still seeing a bad gamma shift with my NVIDIA GPU when hardware acceleration is enabled. You can see this in the PLUGE at 16 seconds here:

Here's my chrome://gpu in 62.0.3169.0 (Official Build) canary (64-bit).

Re #30: Sorry, but I think that comment #33 was made in error, since it refers to a different operating system and use case scenario.

Please follow up in  issue 748076 . In particular, please attach an image of the output that you expect versus the output that you get.

Comment 35 by, Aug 20 2017


I'm getting severe image corruption with enable-gpu-rasterization set. I've mentioned it in a semi-related bug report, but it was ignored.

I disabled it quickly. (I can't disable enable-gpu-rasterization, as that solves other, unrelated, issues.)

This happens also, if you open a second regular window.

cielssky: This is the right site, but the wrong page for this bug report.
Please use the "New Issue" bug at the top of this page to file a new bugreport.
Make sure you include information about what operating system, gpu and monitor profile you are using. If possible, attach your ICC profile to the new bug.
