[Olli Pettay [:smaug][[e-mail]]]

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.)

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.

Comment 4

[Olli Pettay [:smaug][[e-mail]]]

this could be the same as bug 623615. Marking dependency

Comment 5

[Timothy Nikkel (:tnikkel)]

When you put anything inside a rounded rect with overflow hidden it gets slow.

Comment 6

[Timothy Nikkel (:tnikkel)]

This should have gotten better.

Lets keep this bug for the Get Add-ons case.
