Something about this page is making Mozilla peg the CPU.

Comment 1

confirming using build 2002020103 on Win2k.
OS -> All.
This is because of background images (guess they use alpha as they're png-based)
defined in semblance.css:

html {
  background-image: url("fade-to-gnome.png");
body {
  background-image: url("fade-to-grid.png");

Loading site without these images make it work fine (CPU remains at 10 to 0%).

Dupe of bug 96633, bug 90198 ?

I'm seeing the same behavior on build 2002020208 PC/Linux.
We spend most of that CPU time inside:

510   48.6%     nsImageGTK::DrawComposited32
153   14.6%     readv
152   14.5%     gdk_rgb_convert_0888

on Linux.

I've observed loading this page precipitating a crash; though I haven't been
able to nail down the precise circumstances under which the crash will occur.

could patch for bug 143046 help a little (eventhough it doesn't seem to affect
PNGs) ?

This is weird... A week ago I did have problems loading this page, but today
(1/14/03)it loads like a charm on all platforms (Linux, Win XP and MacOS9)using
the 1/08/09 Trunk builds. I wonder if this is not a networking/server problem,
because the page, even with remote URLs, loads quickly as a test case. See
attached testcase.

Carine: What are you testing in your testcase? This is an image compositor bug.
