Comment 23 for bug 81858

I just tested http://digg.com/apple/Apple_Announces_iPhone_2 on a Linux machine using proprietary "nvidia" driver and confirm slowdown of a different type.

I agree with pile0nades that there seems to be two separate issues here. The digg page with 1400+ comments did not ever make Fx unresponsive on my system--it just sucked up a lot of system resources. This does seem halfway reasonable given that there are a whole lot of tiny avatars to render. I think this kind of problem affects all users of Fx on all platforms. I also think that these cases are somewhat more rare.

But the problem with rendering a simple website that makes use of transparent PNGs is absolutely *not* reasonable. I'm talking about the kind of problem you get when visiting linuxactionshow.com, for example. It's not reasonable because it is a very simple website design, and it is also very common. Incidentally, digg.com also makes use of transparent PNGs in a similar way. [I believe this is unrelated to the problem of visiting a digg page with 1400+ comments]
