Bug Description
Binary package hint: firefox
Launchpad.net bug detail pages are painted extremely slowly by Firefox on my machine. I'm running Ubuntu Lucid 64-bit, and I have the proprietary nvidia driver (from the Ubuntu repositories) installed, version "current". The machine has two 8800 GTX GPU's with 768 MB each, so the available graphics power should not be a problem.
It takes many seconds (sometimes tens of seconds) to draw the page, during which the entire computer slows to a crawl. Nothing happens on the screen during this time. Whenever I scroll the page up so that more of the page is revealed at the top of the screen, this is painted extremely slowly as well. Scrolling down (once the page is fully painted) does not produce slow-downs, so the problem appears to be with the content at the top of the page.
It appears to be an interaction between Firefox, Launchpad.net and the proprietary NVidia driver. I don't notice slowdowns like this on any other web page (including other launchpad.net pages). Other browsers, such as Chrome, draw Launchpad bug detail pages with lighting speed. And when I use the nv or nouveau drivers the problem does not appear either.
Since Chrome can paint the pages at fast speeds, Firefox should be able to as well, so I still think this is a Firefox problem.
If there is any way I can determine exactly what it is that is taking so much time and slowing down the entire computer, please let me know! Or if there is any other way in which I can help debug this problem.
