409456 - smooth scroll is slower than non-smooth

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[u294409]

User-Agent:       Opera/9.25 (X11; Linux i686; U; pl; Fedora/8 (Moonshine))
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b3pre) Gecko/2007122105 Minefield/3.0b3pre

I'm using Opera, but I wanted to test Firefox' 3 smooth scrolling and I noticed it's slower than normal scrolling mode.

Slower = non-smooth, with drawing problems, sometimes window is unresponsible, and content is still scrolling in smooth mode.

Reproducible: Always

Steps to Reproduce:
1. enable it.
2. scroll
3. scroll faster
Actual Results:  
it's not smooth, and makes window unresponsible, still scrolls.

Expected Results:  
it's smooth, beautiful, etc :>

Hmmm, I see it's compilation question.
In openSUSE Trunk Firefox was really fast (kernel/glibc i686, rest - i586 packages), even faster than Fedora (kernel/glibc i686, rest - i386 packages).

Ok, I've made simple investigation and I probably have found the issue - mine xorg.conf configuration, but how to make smooth scroll work well if Compiz running :/ ?

Do you still see this problem?  ... Using current version of FF (3.0.4), or 3.1 beta - beta 1 at http://www.mozilla.com/en-US/firefox/3.1b1/releasenotes/ ... or beta 2 available soon 

If you no longer see the problem please close the bug.

3.1b1 seems a lot faster, but when I visit http://livio.blip.pl/ for example, it is no longer fast.

This bug doesn't have enough information to lead to a fix and there are other bugs about "smooth scrolling" performance. Resolving as incomplete.
