Changesets to backout: Bug 722325 https://hg.mozilla.org/mozilla-central/rev/a8b8c4489e4e Bug 722117 https://hg.mozilla.org/mozilla-central/rev/a5569fc4c390 Bug 719177 https://hg.mozilla.org/mozilla-central/rev/2cae7e5c62ae https://hg.mozilla.org/mozilla-central/rev/07bd73451aa4 https://hg.mozilla.org/mozilla-central/rev/13739446fc8e https://hg.mozilla.org/mozilla-central/rev/0246973f2513 https://hg.mozilla.org/mozilla-central/rev/f222fbece983 https://hg.mozilla.org/mozilla-central/rev/8f11aaac24dc Part 4 (outline) in bug 524925 https://hg.mozilla.org/mozilla-central/rev/73eaf1199ff0

Additional fixes on top of the backout, as requested in bug 723669.

Try results pending: https://tbpl.mozilla.org/?tree=Try&rev=fa1a77db5788

Is this something we think we can reinstate later, or is there some fundamental issue with it?

We can reinstate most of it, see bug 723669.

Comment on attachment 594602 [details] [diff] [review] additional fixes Review of attachment 594602 [details] [diff] [review]: ----------------------------------------------------------------- Should we remove nsChangeHint_UpdateTransformLayer and nsChangeHint_UpdateOpacityLayer too? I think we should! It seems to me they currently have the same bug.

Please file a new bug. This bug is only for making UpdateOverflow work for transforms and nothing else. The aim is to merge this to Aurora and leave it at that state for Fx12. Then re-land bug 719177 with some additional fixes (as discussed in bug 723669) on trunk, except for 'text-shadow' which we can handle in bug 723669 (if we decide to do it).

The Try run was green. I installed the Try build on my Nexus and it seems to work fine on sites mentioned in bug 722325, but I'm not exactly sure what to look for. Chris, I'd appreciate if you can verify that. https://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/mpalmgren@mozilla.com-fa1a77db5788/

Feel free to review this patch, or the backout commands + additional fixes patch, whichever you think is easier to review.

(In reply to Mats Palmgren [:mats] from comment #6) > Please file a new bug. Sure, filed bug 724502. I'll try to fix it.

r+ on the patch and backout

This caused bug 722325 to regress again, so I re-instated that wallpaper and filed bug 725664 to fix it for real. The question is - what do we want to do for Aurora? Ship with the wallpaper or revert UpdateOverflow also for transforms?

Wallpaper.

Ok, here's the backout commands for Aurora. Specifically, I'm NOT backing out the wallpaper for bug 722325, which landed independently for Aurora in https://hg.mozilla.org/releases/mozilla-aurora/rev/73f3d8eeb937 On top of that, the same "additional fixes" patch. These changes will make the affected code the same as currently on trunk.
