Default Slow firefox scrolling

Hi NVidia,

this website scrolls poorly slow in Firefox 2.0 and 3.0 on OpenSuse 10.2 and 11.0:
http://www.tempus-vivit.net/taverne/thema/935
My machine is a Geforce 8800GTS with Core2Duo E6400 processor, should be quick enough.

I noticed that scrolling was not perfect before installing the NVidia drivers (173.14.05), but with the drivers it is annoyingly slow, and switching from another firefox tab to this website takes about 2 seconds.

I filed a mozilla bugreport, but I think it could be a NVidia problem: https://bugzilla.mozilla.org/show_bug.cgi?id=441396

Best regards

Wolfgang Knauf

same here, even block all the images by "image like opera".

lots of delay when swithing tabs from/to that page.

err

ArchLinux+177.13+8500GT+AMD 3600+ 64+Dual Core+3G Ram+firefox2.0.0.12

well, thing is different when i use opera9.5.scrolling is perfect (with/without image).

The scrolling for me is about 1.8FPS on a 2.4Ghz Penryn (C2D) with Firefox 3 on 64-bit Ubuntu 8.04. With Opera I get about 15FPS while scrolling. Much faster, but no way near smooth. Using nvidia drivers 173.14.05.

if it's fast with opera 9.5 and slow with other browsers, it's a browser implementation thing.

Not completly, e.g. Opera uses shm-pixmaps to work arround some operations which are (or better were) slow, and are still slow in the nvidia driver.
FireFox3 uses cairo, which itself relies on an efficient render implementation.

However from what the nvidia devs said there should be soon serious improvements.
I am looking forward especially for transformation support.

For fast browsing/scrolling, you'll have to use konqueror (of KDE3, of course).

One bug just got squashed by a Firefox/XUL update (to 3.0.1 / 1.9) in Ubuntu Hardy.

The bottom of Digg.com now scrolls more smoothly on 177.13. T-Mobile.co.uk works at a usable speed, too.
