Im experiencing this issue at the following URL: http://www.techradar.com/
I am accessing it from the UK (it is a UK floating advert about the national lottery that appears to be causing the symptom). On sub pages within the website, I don't experience the symptom but they are non floating: the body of the website scrolls without the advert. On the Home page, the advert scrolls with the body but tries to float to the top portion of the screen. It is on this page that the scroll lag occurs. I am using Firefox 15.0.1. Ubuntu 12.04 with unity desktop ATI Radeon 6800 driver version amd-driver-installer-12-8-x86.x86_64 Workaround attempted: Tried disabling ALL firefox addons - symptom still persistant Tried Firefox on Windows with the same addons and same hardware - Symptom NOT present. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1009201 Title: lagging while scrolling a page. Status in “firefox” package in Ubuntu: Confirmed Bug description: Firefox doesn't scroll the page properly. I may not be able to explain the problem exactly. But here is what happens : 1) Open certain website. For Eg: ubuntuforums.org 2) Try scroll the page down. 3) On screen it looks like it is not scrolled but in fact it would have scrolled down. Ie It appears like GRAPHIC FREEZE. I say it as graphic freeze because I can use the window, for that matter refresh the page etc. This is confirmed after sometime when the page come out that freeze and begins to show the new position of page. Also it can be confirmed by trying to copy a line or opening a link. The link will not be opened because the link would have scrolled to new position and after the window comes out of the 'GRAPHIC FREEZE' you can click on the link from it new posiiton. Also to be noted is that this problem occurs randomly. It creates a very jarring experience. Looks like problem is with Ubuntu/Unity. Because on linux mint this problem is not there ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: firefox 12.0+build1-0ubuntu0.12.04.1 ProcVersionSignature: Ubuntu 3.2.0-24.39-generic-pae 3.2.16 Uname: Linux 3.2.0-24-generic-pae i686 NonfreeKernelModules: nvidia AddonCompatCheckDisabled: False AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
