:aosmond This regressions happens only on the Linux x64 QR platform. Is this something we can fix or should we consider accepting it or maybe back it out?

When bug 1453801 relands, I will ensure this regression is avoided then.

The relanding of the bug's 1453801 new implementation resolved the resident memory regression. As observed by aosmond, we got this regression instead. == Change summary for alert #12873 (as of Mon, 23 Apr 2018 08:57:28 GMT) == Regressions: 26% Images linux64-qr opt stylo 5,346,245.37 -> 6,743,586.09 Improvements: 8% Resident Memory linux64-qr opt stylo 1,171,507,100.03 -> 1,079,530,212.23 For up to date results, see: https://treeherder.mozilla.org/perf.html#/alerts?id=12873

Yes. Unfortunately we'll have to accept the images increase -- if you compare it to linux64, they are now very similar, which is what I would expect. WebRender isn't doing anything special to reduce our rasterized image footprint as compared to non-WebRender. As it turns out, we were actually underreporting WebRender consumption due to bugs I resolved in bug 1453801.
