fast/dom/window-scroll-scaling.html introduced in http://trac.webkit.org/changeset/118569 and it made 300-400 tests flakey on Qt with 1px differences: http://build.webkit.sed.hu/results/x86-64%20Linux%20Qt%20Release/r118577%20%2837891%29/results.html I tried to skip fast/dom/window-scroll-scaling.html locally and then everything works fine, as before r118569. Have you got any idea what happened?
I skipped it to make bots happier a little bit - r118727. Please unskip it with the proper fix.
I think 87680 will fix this.
Bug 87680.
