Description Timvde 2013-05-31 07:49:35 PDT
It looks like bug 867770 introduced a regression of about 40MB on AWSY after TP5, before closing the tabs. The misc graph shows almost all of the lost memory in heap-unclassified.

This should fix the bug, though I still need to verify that on AWSY. We were always optimizing background images to image layers, which we know will cause more memory use—which is the reason for the pref I added in the first place, actually.

BTW: Is there a bug on Image* (ImageLayer, ImageContainer, Image) not reporting their sizes?
Comment 3 Andrew McCreight [:mccr8] 2013-06-02 20:03:03 PDT
Hey John, could you annotate AWSY with the bug number of this regression?  Or the regressor, I guess.  Thanks.

Thanks for quickly investigating and patching this regression, Joe!

I'm running this on AWSY, but it is unlikely to make things *worse* so I've pushed it too.

This seems to have fixed the regression.
