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,win64 -u none -t svgr-e10s[10.10,Windows 8],dromaeojs-e10s[10.10,Windows 8],other[10.10,Windows 8] --rebuild 5  # add "mozharness: --spsProfile" to generate profile data

(we suggest --rebuild 5 to be more confident in the results)

To run the test locally and do a more in-depth investigation, first set up a local Talos environment:
https://wiki.mozilla.lorg/Buildbot/Talos/Running#Running_locally_-_Source_Code

Then run the following command from the directory where you set up Talos:
talos --develop -e [path]/firefox -a dromaeo_css:tabpaint

(add --e10s to run tests in e10s mode)

Making a decision:
As the patch author we need your feedback to help us handle this regression.

this only seemed to affect aurora when it landed there and is now on beta!

:nical, can you investigate this and determine why this is happening?

oh, I am sorry- I thought I had collected more data and realized that this is related to the uplift, not this patch.
