Propane burning over 20% of my cpu cycles

So, propane is taking 20-30% of my cpu cycles, but only when i have one particular tab open. If I go to a second tab that I have open, cpu usage drops back down to < 1%. Anyone else experienced this? Only thing different about offending tab is it has a few more users (maybe 10 vs 5 in the other) and someone posted an animated gif.

    Hi Chris,

    Yes, animated gifs consume a lot of CPU while they are on-screen. You can see the same effect if you view the same Campfire room in Safari.

    If you right-click on an image you can select the menu option of "Hide annoying image" and it will cause the image to be replaced with a link.

    So, no fix planned for this? I know my browser doesn't gobble cpu if I'm
    viewing a page with an animated gif.

    Hi Chris,

    If your browser is Safari, then it does gobble the CPU when viewing animated gifs in Campfire (though it's a sub-process called "Safari Web Content").

    Propane currently uses the same rendering engine as Safari (WebKit) which is why it behaves the same when presenting animated gifs.

    So the fix, as such, is to move away from browser-based rendering. I'm working towards it.
