.11 - 9 .21% Resident Memory (linux64, linux64-stylo-sequential) regression on push ba0c3051a9ed (Fri Oct 12 2018)
We have detected an awsy regression from push: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=81c3640eaebc47516247f546b2203ec550fdd37a&tochange=ba0c3051a9ed3b8e3120eb25d770ea459d3f719d As author of one of the patches included in that push, we need your help to address this regression. Regressions: 9% Resident Memory linux64 opt stylo 550,110,125.90 -> 600,775,321.51 9% Resident Memory linux64-stylo-sequential opt stylo-sequential 538,109,206.50 -> 587,153,892.85 You can find links to graphs and comparison views for each of the above tests at: https://treeherder.mozilla.org/perf.html#/alerts?id=16760 On the page above you can see an alert for each affected platform as well as a link to a graph showing the history of scores for this test. There is also a link to a treeherder page showing the jobs in a pushlog format. To learn more about the regressing test(s), please see: https://wiki.mozilla.org/AWSY/Tests

Difference of visual seemed to cause the memory regression.
The visuals can have various buffers like front/back buffers, depth, stencil. The selected buffer depends on the actual gfx driver. With this patch we'll always use GL/WebRender compatible visuals which can raise the memory consumption.
I don't think there's a fix for that unless we disable the HW acceleration.
(In reply to Martin Stránský [:stransky] from comment #3) > I don't think there's a fix for that unless we disable the HW acceleration. So... Can we call this a wontfix then?
Is there a reason why libGL is loaded even when GL rendering is disabled?
(In reply to Karl Tomlinson (:karlt) from comment #5) > Is there a reason why libGL is loaded even when GL rendering is disabled? Yea, we could disable to load libGL when GL rendering is disabled.

I confirm the push from comment 11 fixed the regressions.
