Reproducing and debugging the regression:
If you would like to re-run this Talos test on a potential fix, use try with the following syntax:
try: -b o -p macosx64 -u none -t svgr  # add "mozharness: --spsProfile" to generate profile data

To run the test locally and do a more in-depth investigation, first set up a local Talos environment:

:kats, can you comment on this- I wonder if the additional regressions showed up later and we fixed svg and not cart/tpain/*scroll* ?

All the OS X 10.6 regressions listed on this page were fixed by bug 1139033, and I expect the OS X 10.8 ones will be as well, once the data gets generated. If you look at the graphs you'll see that all the 10.8 data is a few days old and hasn't get caught up to March 5, which is when bug 1139033 landed. If these regressions persist after that I can look into it.

ok, this is fun- osx 10.8 is now shut off and replaced by osx 10.10, so lets just assume all the 10.8 regressions are fixed :)

both osx 10.6 regressions have been fixed- should we close this bug out?

I think so.
