web browsers supporting opacity very slow


why are browsers that support opacity levels very very slow in linux?
in xp they are fine this includes firefox
on sites like myspace with these settings active it causes increadible cpu usage and near unusable scrolling. it is making it unbarable to use.

here is an example site i found which is very slow
http://jeffhowden.com/code/css/forms/
this is across the board as opera suffers from this issue also. any ideas?

fedora fc 6
nvidia fx5200
firefox 1.5.10 fedora build
Mozilla Firefox 1.5.0.10, Copyright (c) 1998 - 2007 mozilla.org
Opera 9.10 . Build 521 for Linux. Qt library 3.3.7.

I'm running FC6, with Firefox 2 and that site is fast (as fast as a text-only site). I'm running on a 6-year old laptop with a P4M 1.7GHz and an Nvidia 440Go. A lot less resource than you have. I suspect you've got a problem somewhere. Is your system up to date? Are you using the NVidia driver?

i have the latest patches and i use the nvidia kmod from the livna repository. here is a better website for hammering performance http://profile.myspace.com/index.cfm...endid=59274363

i would be really interested in your xorg if that is possible as it seems this issue is cross browser then there is a chance it is an xorg related issue
many thanks,

That site peaks my CPU for 5 seconds while loading, but scrolling is not a problem. Maybe you should try Firefox 2 (I don't have any systems running Firefox 1.5 anymore). On Fedora Core 6:

yum -y --disablerepo=* --enablerepo=development update firefox

well thanks very much for the update code but the issue still has not been completely resolved it is better but not fixed. pages using the opacity css tags still stutter but nothing near to how bad it was so for that i thank you

I'm also running Firefox on FC6 on a 3.4GHz, with my onboard Intel 945 chip. The sites you've listed seem fine to me. There is a small amount of jitter on those sites, but it seems pretty normal as far as I can tell.
