Description:
compositing/contents-opaque/body-background-skipped.html
compositing/rtl/rtl-fixed.html
compositing/contents-opaque/body-background-painted.html
compositing/fixed-image-loading.html

These tests passed consistently until the change at 254304@main, when they began to fail consistently.

Reproduction steps:
I can reproduce this on 254304@main but cannot reproduce it on 254303@main or earlier.

Command: 
run-webkit-tests -1  --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --iterations 50 -f --no-retry compositing/contents-opaque/body-background-skipped.html

Result: 
Regressions: Unexpected text-only failures (1)
  compositing/contents-opaque/body-background-skipped.html [ Failure ]
