Firefox performance regression for google reader

[puntium]

Binary package hint: firefox

Using google reader in firefox 3.5 in karmic is _much_ slower than using it firefox-3.5 (shiretoko) in Jaunty. Especially when scrolling the articles list on the right side (in expanded mode). The screen refresh is painfully slow.

Moving to firefox-3.5

Thank you for reporting this to Ubuntu. What video driver do you have?

lspci says:

0a:00.0 VGA compatible controller: nVidia Corporation G73 [GeForce 7600 GT] (rev a1)

I'm using the "nvidia" driver. Xorg.0.log says:

(II) NVIDIA dlloader X Driver 180.44 Tue Mar 24 05:51:43 PST 2009
(II) NVIDIA Unified Driver for all Supported NVIDIA GPUs

A colleague mentions that this issue may have to do with the move to GTK 2.18. He has seen similar issues on another non-Ubuntu box that were introduced with a GTK upgrade.

Got same problem using ATI/AMD FGLRX driver.

Same here

00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02)

It's particularly noticable with Google Reader, but the scrollbar has a somewhat sluggish feeling to it with all websites.

I should've mentioned that this happens regardless of whether compiz is enabled or not.

The development versions 3.6 and 3.7 from the ubuntu-mozilla-daily ppa work better with Google Reader. Performance is as good as it was with Firefox 3.0 on Jaunty.

I'm also having this problem with the NVIDIA proprietary driver version 185. Also, Google Docs seem to have the same issue. They were a bit slow in FF 3.0 but are much worse now.

I can confirm this bug. Please see my comment #95 on this bug for the list of things I've tried:

https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/217580

I posted there because I figured it was the same bug but it may be different.

Using 9.10 x86_64 (fresh install) with NVidia GeForce 8500 GT based card.

BTW, I was using ff-3.5 on Jaunty (shiretoko), and I did not observe this problem, so I suspect firefox isn't actually the problem. It's something in the environment that has changed (perhaps slightly supportive of the gtk regression theory)

I am experiencing the same thing with Google Reader, I have this bug with extensions or no extensions in Firefox 3.5.3 and 3.5.4. I recently did a fresh install to Ubuntu 9.10 , but; I was experiencing this in Ubuntu 9.04. It does not happen in Firefox 3.6 beta or 3.0. I am using a Nvidia 7800gt I had this bug using the NVIDIA-Linux-x86-185.19 and NVIDIA-Linux-x86-190.32 drivers.
