.65% osx paint regression on Aurora (v .33) and Beta (v .32) on August 18th
there are three bugs relate to this, bug 1016434, bug 1045591, and bug 1054359. here is a graph showing the regression: http://graphs.mozilla.org/graph.html#tests=[[82,52,24],[82,52,21],[82,53,21],[82,53,24]]&sel=none&displayrange=30&datatype=running This seems to be restricted to OSX (both 10.8 and 10.6).
:jaws, :jandem, can you guys comment on the chance one of those patches caused a perf regression?
Zooming out to 90 days, it looks like it is due to bug 1016434. The loading throbbers used to be an animated PNG, then we changed them to be a static PNG that gets animated via CSS animations. Bug 1016434 backed out that change due to some blurriness in the animation that some people reported seeing. So this is a regression in the correct definition, but it is also just returning back to the previous state as evidenced by this screenshot, http://screencast.com/t/wPss5554e4 I would call this bug reso-worksforme or something of that nature. The perf should get better when we figure out a fix for the blurriness and are able to keep the CSS-animation'ed throbbers.
I think for beta it isn't an issue, but for aurora, we have a higher value, especially on 10.8
it is a smaller regression, 5-6 percent.
Maybe one of the other patches were the cause for the Aurora regression.
We have long since shipped this code. Are there any concerns with marking this as wontfix?
I am fine with wontfix.
