185.18.04 - Firefox and poor scrolling performance on some pages

[karolbe]

Hello

I have noticed that on a following web page:

http://trac.edgewall.org/report/11

displayed in Firefox scrolling is very slow, CPU usage jumps to 100% and so on. Do you experience it too? My system is Ubuntu 9.04 + Firefox 3.1 beta 3 + NVidia 185.18.04 (hardware is NV 9600M GT)

Hi,
I use Nvidia driver 185.18.04 and these:

# aptitude search ^iceweasel$ -F '%p %V %v'
iceweasel                                                                                3.0.9-1    3.0.9-1
# aptitude search ^xserver-xorg$ -F '%p %V %v'
xserver-xorg                                                                             1:7.4+1    1:7.4+1
# aptitude search ^xserver-xorg-core$ -F '%p %V %v'
xserver-xorg-core                                                                        2:1.6.1-1  2:1.6.1-1

+ lastest Adobe 64bit flash player plugin from 2/24/09

I have all compositing effects disabled.

Since this driver I have smooth scrolling and only 10% cpu usage while playing flash videos.

For me, this is the best available driver so far.

Regards,
Sascha

looks like another background image scrolling problem.

i can get smooth result by disable all the image elements (using image like opera extension-choose don't load image).

if enable all the images, then i have same result as you

debian sid+185.18.04+8500GT+swiftfox3.0.10pre

No problems here. (185.18.04, 8600mGT, Firefox 3.5beta5pre)

Here is something I've noticed in KDE 4: Grab an edge of firefox and pull it back and forth for awhile. It starts off resizing smoothly, but after maybe 15 seconds or so, it gets very skippy and jerky.

I've noticed this in KDE 4 with the 185.18.04 drivers, others may be affected as well.

Anyone else able to reproduce this? with other drivers or under other window managers?

Konqueror doesn't seem to do it. Synaptic does though, which makes me wonder if it's related to GTK reskinning somehow.

personman: I get similar effect when dragging elements from firefox - it is slow and after a while kde disables compositing automatically. But it is unrelated to this issue.

I get exactly the same thing, and I have since I started using Linux around the time of the release of the 180.06 drivers.

No problems here: Fedora 10 x86_64, 9800GTX+, 185.19, Firefox 3.0.10, Gnome, compiz enabled

30% CPU usage on that page versus 15% usage on this thread. Powermizer stays on level 0. (Level 0 = 400mhz, level 1 = 740mhz)

Scrolling on that page works without issues for me: Gentoo x86_64, GTX 280, 185.18.04, Firefox 3.0.9, Gnome 2.26 with compiz.

No problem here: Arch Linux, 8600M GT, 185.18.04, Firefox 3.0.9, Xfce (with compositing turned on).
