[gentoo-user] Gtk+ update results in slow Firefox

[gentoo-user] Gtk+ update results in slow Firefox

[Nikos Chantziaras]

There was an update to Gtk+ today (from 2.16.6 to 2.18.3).  After 
performing the update, Firefox (3.5.4) is slow as molasses when 
scrolling in some pages.  Example:

   http://www.simplemachines.org

(Try to scroll up/down).

Anyone else noticing this or is it just me?  I'm on AMD64.  I've rebuilt 
xulrunner and Firefox after the Gtk+ update just in case, but it didn't 
make any difference.

do you have a bigger page with more scrolling showing the problem?
because it seems to be fine here.

scrolls without any lag. Instant response. No lag at all. 
Even with effects turned on there is no lag.

Then I wonder what's wrong here.  It's so slow, that if I scroll the 
mouse wheel up/down quickly a few times, Firefox is still scrolling for 
several seconds after I stopped using the wheel, trying to catch up. 
Starting with a clean profile didn't help either.

I've updated to Firefox 3.6 Beta (mozilla overlay) and this version 
restores the speed again.  I guess I'll stay with this beta since 
(fortunately) the add-ons I use work with it.

So I guess problem "solved." :P

Gah, the Flash plugin is very buggy with 3.6 (rendering corruption).  I 
reverted to 3.5.4 and downgraded to Gtk+ 2.16.6 and gtkmm 2.16.0 instead.

Any pointers at to what might be wrong are still welcome.

Shot in the dark here.

NVidia updated their drivers at about the time you started having
problems. Their latest driver update changed the permissions on
/dev/nvidia0  nvidiactl ; resulting in VERY slow scrolling response on
my box (amd64) using googleearth. Changing the permissions to crwxrw-rw-
resulted in instant speed up; you may get by with r--r-- (?).

Thanks, but that's not it.  I'm on ATI and /dev/ati/card0 has the right 
permissions.  And it works just fine with older Gtk+, just not with newer.

I don't have that device on either of my systems using a GeForce 7300 GS. Nor 
can I find an nvidiactl.

That device appears when you use the NV proprietary driver.

There are basically three options with an NV card:

- use the generic built-in driver
additionally,
- use the additional, open-source NV drivers.
or
- alternatively use the proprietary NV driver.

This may be useful: <http://en.gentoo-wiki.com/wiki/Nvidia>

FWIW, the NV drivers are blocked in portage for my hardened AMD64, so I
get the drivers here:
<http://www.nvidia.com/object/unix.html>

I should have said that I'm using x11-drivers/nvidia-drivers-190.42-r2, which 
I thought was the proprietary driver.

I forgot to mention that the problem is only really apparent with 
"smooth scrolling" enabled (Preferences->Advanced->Use smooth 
scrolling).  It was a bit slow before the update too, but nothing 
serious, but now it's *extremely* slow.

'sanften Bildlauf aktivieren'? Turned it on, restarted firefox. There is a 
short jerk when scrolling the page for the first time but after that everything 
is quick.

Nope, no problem here.

Same versions as you, on ~amd64 with nvidia proprietary drivers and 
xorg-server-1.7.1
