These three layout tests fail when you run them on a Retina Macbook Pro or any Mac running in HiDPI mode:
ietestcenter/css3/flexbox/flexbox-align-baseline-001.htm
ietestcenter/css3/flexbox/flexbox-align-center-001.htm
ietestcenter/css3/flexbox/flexbox-align-center-002.htm
The results seem to indicate pixel cracks are the problem.
It would be nice in the short term to have a new directory like the platform directory for test results that are specific to different deviceScaleFactors.

We don't have these as failure on macOS text expectation but have it on iOS:
https://searchfox.org/wubkat/source/LayoutTests/platform/ios/TestExpectations#1362
Are these [ ImageOnlyFailure ] tracked with this bug? Or we can close this because this was for Mac?

On macOS we haven't run tests in HiDPI mode for a very long time; but we do for iOS.
That said, this definitely still occurs: imported/w3c/web-platform-tests/css/css-flexbox/align-self-001.html has a whole load of cracks that makes it fail at 3x — and test results look much worse at 3x than 2x.
