XenForo is some kind of forum software, and it seems to have some pretty bad checkerboarding problems when scrolling quickly across the page. Here's an example page:

Scrolling bottom-to-top seemed worse, but maybe that's just me. This is on OSX.

I profiled this locally and we're spending a lot of time allocating tiles. That should be fixed by increasing the tile size (bug 1188995) or we should increase the pool size.

Another interesting thing to note is that we're spending time doing antialiased rendering nsDisplayBackgroundColor::Paint which is surprising to me and probably worth investigating.

XenForo sites have actually worked fine for me for quite a while, so I'm just going to switch it to WFM. Hooray!
