Extremely slow tab switching on Launchpad pages

[Lech Lorens]

Binary package hint: firefox-3.5

Rendering Launchpad pages is extremely slow in Shiretoko. E.g. Shiretoko takes about 30 seconds to switch between tabs https://launchpad.net/ubuntu/+source/firefox-3.5 and https://launchpad.net/ubuntu/+mentoring, while in normal situation a tab switch takes less than 1 second. When Shiretoko freezes to handle the tab switch, top reports that the X.org process takes up 100% CPU. I am running X.org (version 2:1.6.0-0ubuntu14) in a dual-head setup with one of the monitors rotated by 90° with Xinerama enabled on Nvidia GeForce FX 5200. I am using the 173.14.16 Nvidia binary drivers (nvidia-173-kernel-source - version 173.14.16-0ubuntu01).

Ubuntu 9.04.
Package versions:
firefox 3.5.1+build1+nobinonly-0ubuntu0.9.04.1,
nvidia-173-kernel-source 173.14.16-0ubuntu01

Thank you for reporting this to Ubuntu. This might be related to your graphics driver. Could you try the nv driver to see if the same thing happens? Also, bug 398893 is open to update the nvidia-173 drivers to the latest version in Karmic.

Indeed, it seems to be a problem with the Nvidia graphics driver. I switched to nouveau and the problem disappeared.
Thank you!

Moving to nvidia graphics package as the problem is there. Could be the update will fix this...

Is this a dupe of bug 223238?
