Created attachment 137170 [details] Simple test case There should be no green outside the red box.

Created attachment 137647 [details] WIP patch, the logic is not bullet-proof enough as-is.

Created attachment 138469 [details] Better fix 2: Keep track of whether we have skipped creating a RenderLayer and create them when needed.

Seems related to bug 81989.

Comment on attachment 138469 [details] Better fix 2: Keep track of whether we have skipped creating a RenderLayer and create them when needed. Removing the review flag on this patch. I will post a patch rolling out r110072 and some of the follow-ups instead as it came under my attention that it caused other regressions.

Created attachment 139286 [details] rollout 110072 take 1.

CC'ing some bot maintainer so that they see the tide coming as the next roll-out should be good to go.

Created attachment 139554 [details] rollout 110072 take 3. Should be fine now.

Comment on attachment 139554 [details] rollout 110072 take 3. Should be fine now. For the record, I have forgotten to remove hasOverflowClipWithLayer() thus leaving tons of unneeded NULL-checks. I will change that prior to landing.

(In reply to comment #14) > Committed r115846: <http://trac.webkit.org/changeset/115846> Some of the tests this patch unskipped now fail on Mac bots (see <http://build.webkit.org/results/Lion%20Release%20(Tests)/r115846%20(8073)/results.html>). Do these just need new baselines, or are these legitimate failures?

Do these just need new baselines, or are these legitimate failures? Most of them just need a rebaseline (which I wouldn't have expected as they were not rebaselined since r110072). Only tables/mozilla/bugs/bug4527.html seems to be failing because of some other cause. The change in media/audio-repaint.html seems strange but not unseen (the renderers are removed from the dump instead of being reparented under a RenderLayer). I was going to disable some of the tests to make the bots happy again but I missed the differences as the console didn't show the new failures :(

I updated the Qt results - http://trac.webkit.org/changeset/115875 Have you got any idea why have we more Qt specific expected results after this change?

(In reply to comment #18) > I updated the Qt results - http://trac.webkit.org/changeset/115875 > Have you got any idea why have we more Qt specific expected results after this change? We haven't rebaselined Chromium yet which may explain for the extra baselines. I don't expect to do the Chromium rebaselining today as I have other stuff on my plate.

Mac results updated in: http://trac.webkit.org/changeset/115879 http://trac.webkit.org/changeset/115885 http://trac.webkit.org/changeset/115890
