Issue 71276: Scrolling web pages is choppy with Nvidia

Reported by, Jan 29 2011

Issue description

Chrome Version: 9.0.597.83 beta
Is this the most recent version: Yes
OS + version: Ubuntu 10.04 (up to date)
CPU architecture (32-bit / 64-bit): Intel(R) Core(TM) i7 CPU M620@2.67GHz
Window manager: Compiz
Behavior in Linux Firefox: The same page scroll smoothly

What steps will reproduce the problem?
1. Open Google Chrome browser with a dual screen setup
2. Browse to any pages with is big enough to scroll
3. Start scrolling using the mouse wheel OR the elevator
4. The refresh rate or drawing is to slow.

What is the expected result?
It' should scroll like firefox.
The CPU usage should stay very low (under 20% for firefox and Xorg)

What happens instead?
The scrolling in Googl Chrome is choppy.
The CPU usage of Xorg is near 100%

My believe is that chrome is not using the hardware acceleration to properly scroll the page, resulting in a high CPU usage and a very slow redrawing of the page.

Graphics Card: nVidia Corporation NVS 3100M (rev a2)
Driver: I use the proprietary driver available in the Ubuntu default repository. (version 195.36.24)

I test it with and without Compiz enabled.

Might be related to #13662.

Notice, when forcing the compositing acceleration using the `--enable-accelerated-compositing` and browsing The scrolling is very smooth.

I can confirm this, but it only happens after I suspended my laptop once.

(Chrome 11.0.686.3 dev, Ubuntu 10.10 on a Lenovo T410, 64 bit, Core i7, nVidia GT218 [NVS 3100M])

This also affects Flash video performance, but not HTML5-video, which is running smoothly even fullscreen and in HD.

Comment 3 by, Mar 13 2011

I also experience this.  Scrolling works fine until after suspend, then it's slow and choppy.

Chromium 10.0.648.127 (76697) Ubuntu 10.10, x64

Lenovo T510, i5, NVS 3100

Comment 4 by, Mar 16 2011

I can confirm this on a Lenovo T510, with an i7 and NVS 3100M chipset.

System works as expected until suspension, then Chromium has unacceptably slow scrolling. Attempted to fix things by setting the GPU Acceleration flags in about:flags; while it helped a touch, the problem still exists.

Chromium 10.0.648.133 (77742) Ubuntu 10.04, amd64.

Comment 5 by, Mar 27 2011

I have the same issue on a Lenovo T410, i7 and nVidia NVS 3100M. I tried both the repository and latest versions of the nVidia driver, doesn't fix the issue. 

Suspending is unusable for me and I have to reboot instead, which is very annoying. I'd greatly appreciate if this is fixed, since I really like Chrome so far.

Chrome 10.0.648.204, Ubuntu 10.04 (2.6.32-30 amd64), nVidia 260.19.36

Comment 6 by, Mar 30 2011

I can confirm this, acer aspire 5738g, intel t6400 cpu, nvidia g105m. Slow scroll only when the graphics/memory/processor clock of the gpu is the lowest

Comment 7 by Deleted ...@, Mar 30 2011

Lenovo T510 i5 and nVidia NVS 3100M, the same problem.

Comment 8 by, Apr 5 2011

I can confirm this. It only occurs after resuming from suspend as well.

(Chrome 12.0.712.0 dev, Ubuntu 10.10 on a Dell Latitude E6410, 32 bit, Core i7, nVidia GT218 [NVS 3100M])

Comment 9 by, Apr 12 2011

I can confirm this. HP EliteBook 8540p, NVIDIA NVS 5100m, Intel Core i5-520m, 64bit. Chromium 12.0.725.0. Sometimes slowed down after fresh start and always slowed after suspend.

I've found that disabling hyperthreading in the bios fixes this. This script also works too and is for a Thinkpad W510 but you should be able to be adjusted for your system if needed.

# Disable hyper-threading processor cores on suspend and hibernate, re-enable them
# on resume. Presumably helps for buggy nvidia behaviour.
# This file goes into /etc/pm/sleep.d/

case $1 in
echo 0 > /sys/devices/system/cpu/cpu1/online
echo 0 > /sys/devices/system/cpu/cpu3/online
echo 0 > /sys/devices/system/cpu/cpu5/online
echo 0 > /sys/devices/system/cpu/cpu7/online

echo 1 > /sys/devices/system/cpu/cpu1/online
echo 1 > /sys/devices/system/cpu/cpu3/online
echo 1 > /sys/devices/system/cpu/cpu5/online
echo 1 > /sys/devices/system/cpu/cpu7/online

Also make sure when you save this script to also chmod +x /etc/pm/sleep.d/

Comment 12 by, Apr 12 2011

the occurence of this problem has changed for me: now the slow scrolling happens every now and then for apparently no reason. Visiting fixes it for all open windows/tabs.

12.0.725.0 dev on Lenovo T410, nVidia GT218 [NVS 3100M] (rev a2), proprietary graphics driver, Ubuntu Maverick

Comment 13 by, Apr 13 2011

Because graphics/memory/processor haven't the lowest clock. Slow scroll appens only with the lowest clock (go to System → Administration → nVidia X Server setting and open the Powermizer tab)

Comment 14 by, Apr 16 2011

Same issue, lenevo t410 with nvidia, tried setting powermizer and the script here both did not work.

Comment 15 by, Apr 29 2011

I have the same issue under Ubuntu 11.04, nVidia driver 270.41.06, GPU NVS 3100M. Laptop + monitor.

Comment 16 by, May 11 2011


Ubuntu 11.04 nVidia 270.41.06, Quadro FX 2800M on a HP Elitebook 8740W

Maximum Powermizer performance did not help.

Comment 18 by, May 18 2011

I just updated to 270.41.06 of the nVidia driver, the problem is still there. I am forced to use Firefox 4, because this renders Chrome unusable for me. Disabling hyperthreading before going into standby doesn't fix it.

Why is this bug still in the 'unconfirmed' state? I believe enough people reported the same problem.

Comment 19 by Deleted ...@, May 23 2011

The same for me!

Comment 20 by, May 23 2011

Chrome is slow after suspend+resume

Lenovo W510
Ubuntu 11.04, kernel 2.6.38-8-generic, i686
Quadro FX 880M
NVIDIA Driver Version: 270.41.06

Comment 21 by, May 23 2011

Chromium is very slow after resume. Lenovo W510.

Comment 22 by, May 29 2011

i haven't tried to confirm it relative with resume. but i notice a way to reproduce easier:
1. open a new tab
2. open a new url on the tab
3. scroll
the problem may seems gone after the initial reproduced lag but if you reopen a new tab doing step 1 2 3 you can reproduce it

this is windows 7 x64, 9600 GSO, AMD B99 x4. i don't think it as hyperthread specified, as there's no hyper thread with AMD cpu

Comment 23 by, Jun 2 2011

I have the same problem - scrolling is slow and choppy

Ubuntu 11.04, AMD64, 2.6.38-8-generic
NVidia GeForce 310M, Driver 270.41.03
Chromium 12.0.742.68

I'm starting to doubt that this is a Chromium issue though.  While Firefox is fine, I believe I'm experiencing the same behavior, at the very least, in evince and LibreOffice Calc.  I think this is an NVidia issue as I've had kernel panics on this machine in the past due to the NVidia driver while suspending.

Comment 24 by Deleted ...@, Jun 15 2011

I can confirm that scrolling of chrome is choppy after suspend. But I also think, this has more to do with nVidia than with chrome. FireFox 4 seems not to be laggy, but if you have a closer look, you will notice that it needs a lot of CPU usage while scrolling, like chrome (30% CPU usage). After reboot both browser work great again and when i scroll it needs not more then 5% CPU usage.

Ubuntu 11.04, i686, 2.6.38-8-generic
HP Elitebook 8540p, i7, NVS 5100M, dual screen
Chromium 12.0.742.91

I think nVidia still provides better linux support than ATI. With an ATI card it is even not possible to suspend.

Google is such a great Linux friend as we all know, why do they not sell hardware? :D
so that we finally have hardware which supports linux 100%.
When i bought this notebook i spend about 400€ more just because i wanted better Linux support than with my last notebook (ATI card, AMD processor, Toshiba), if Google would sell special Linux notebooks (maybe a bit more expensive then a normal one), i think a lot of people would buy it.

Comment 26 by, Jun 15 2011

I have same EliteBook and workaround mentioned in fixed this issue for me. I disable and then re-enable HT cores on startup and scrolling is still smooth. I also disable them before suspend and after resume re-enable them.

Comment 27 by Deleted ...@, Jun 17 2011

Yes, i blamed the wrong company, disabling HT before suspending helps, so its the intel driver which is buggy and not the  nvidia, :)

Comment 33 by Deleted ...@, Jul 11 2011

Same here on Ubuntu 11.04 64 Bit with Nvidia Twinview. After every suspend scrolling is slow.

Comment 34 by Deleted ...@, Jul 12 2011

In addition: A resume from hibernate does NOT cause slow scrolling!

Comment 35 by, Jul 25 2011

I have the same problem after suspend/resume though it also seems to happen after a while for no reason.  Rebooting solves the problem for a while.  Here are my specs:

Ubuntu Linux 11.04 with Gnome 3 (also tested on Gnome 2)
Chrome 13.0.782.99
nvidia 275.19 (also occurred with previous versions)
nVidia Corporation G84M [Quadro NVS 140M] (rev a1)

Firefox does not have the problem.

Good news: issue seems to have gone away for me.

Thinkpad W510

Agreed, I actually forgot about this issue and I use chrome daily.

Due to the age of the issue, changing the priority to P3, however because it has at least 10 stars, marking it for review.

Comment 40 by, Aug 10 2012

Status: Unconfirmed

Comment 41 by, Aug 10 2012

This is resolved for me too. I can't remember when it got resolved though. I am currently using Chrome 21.0.1180.57 on Arch 64-bit, Linux 3.4.7 and xorg 1.12.3.

Comment 42 by, Aug 11 2012

This has been resolved for me too.  GPU acceleration also helps for those configurations it works on.

Still happens to me on Ubuntu 15.10 and the latest chrome.

Comment 46 by, Aug 23 2016

Same for me.

Have jerky scrolling animation (low FPS)and GPU process 100%, while playing video in other chrome window.

Have to use firefox, because it very annoying for me. Please do something.
