fast/backgrounds/hidpi-bitmap-background-on-subpixel-position.html This test became a flaky failure after commit r257840 I was able to reproduce this failure by running the test in debug. It does not reproduce on r257839 but it does reproduce on r257840. History: https://results.webkit.org/?suite=layout-tests&test=fast%2Fbackgrounds%2Fhidpi-bitmap-background-on-subpixel-position.html&platform=ios Diffs: attached.

This is very suspicious. I am going check if it is a sim only failure.
