Scrolling the Get Add-ons page in about:addons is slow
Mozilla/5.0 (Macintosh; Intel Mac OS X 10.5; rv:2.0b10pre) Gecko/20110124 Firefox/4.0b10pre The page seems to be this https://services.addons.mozilla.org/en-US/firefox/discovery/pane/4.0b10pre/Darwin Based on Shark profile 26.9% is taken by painting background (including 17.5% PaintGradient) 17.5% is taken by painting borders. 10.4% is taken by nsTextFrame::PaintOneShadow and things under it 7.8% is taken by nsDisplayBoxShadowInner::Draw and things under it (I'll file another bug for the usability issues.)
Summary: Scrolling the addon page is slow → Scrolling the addon page in about:addons is slow
If I load just https://services.addons.mozilla.org/en-US/firefox/discovery/pane/4.0b10pre/Darwin, scrolling is quite fast. So something in about:addons triggers slow paths.
Bug 623615 is the same issue for the list view, any reason to think this would be something different?
I don't think so. AS given by comment 1 the problem is not in the discovery pane but only happens when content is presented in our pane with rounded corners.
When you put anything inside a rounded rect with overflow hidden it gets slow.
This should have gotten better.
Lets keep this bug for the Get Add-ons case.
