User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007 Firebird/0.7 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007 Firebird/0.7 On the page www.dafc.co.uk there is a large flash animation at the top of the page, along with several smaller ones down the righthand side. With smooth scrolling turned on, it is impossible to scroll the page using the page-down button or the mouse wheel. The only way to scroll the page is to use the scroll bar. If smooth scrolling is turned off, scrollign works fine. This problem seems to be related to the large flash animation at the top of the page which does rapid updating - scrolling further down the page beyond this gives us back normal scrolling capability, albeit very slow and jerky. Reproducible: Always Steps to Reproduce: 1. Turn smooth scrolling off. 2. Make sure you have the flash plugin installed 3. Visit www.dafc.co.uk . 4. Try to scroll down the page using either the mouse wheel or page-down keyboard button - page scrolls down fine as it should. 5. Now enable smooth scrolling and move to top of page. 6. Try to scroll down the page as before - note how mouse wheel and page-down key have no effect.

Forgot to mention that CPU usage is maxed out on this page as well - even when Firebird is minimized or not visible on the screen. This severely reduces the responsiveness of the whole system - Firebird and all other applications running on the system.
scrolling WFM Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6a) Gecko/20031024 Firebird/0.7+ CPU is also 100% used, but system remains completely responsive, and other programs can get processor time if they need it.

WFM 2003-10-30 build on WinXP. Please try a current nightly build with a fresh profile.

Still showing original symptoms with build ID: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6a) Gecko/20031030 Firebird/0.7+ N.B. This is a Firebird build, not plain Mozilla - I haven't tried this yet. I am currently using Firebird as my primary browser and am very happy with it apart from this minor problem.

I've just tried the latest Firebird build on another Windows XP machine that I have (a slower one) and it is showing the same symptoms when visiting dafc.co.uk . Again, disabling smooth scroll gives me back the ability to use the mouse wheeel and page-up/down keys.
Since this is happening for both mozilla and firebird, I'm sending to browser. What are the hardware specs of your computers? I wonder if this is a performance related issue.

My main computer is an Athlon 2000+ with 1 gig of memory and nVidia GeForce 400 AGP graphics card, so I doubt this is a performance related issue. My other PC is a Duron 850MHz with 512MB and a Voodoo 3 18MB PCI graphcis card. Even if this were a performance related issue, I would still not expect smooth scrolling to be completely disabled. I should still be able to scroll the page.
I agree, just because two of us can't see the problem at all I'm trying to think of reasons it might be occuring for you, and not for us. Adding keyword qawanted to get some help isolating the issue.

Just to re-interate - the home page at www.dafc.co.uk is the only place that I am seeing this bug, all other flash enhanced pages seem fine. Also, I'm using Windows XP service pack 1 with all the post SP1 patches applied. Hopefully this information will help folk reproduce this.

I was able to reproduce this bug on the following: Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.6) Gecko/20040113 and Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.5) Gecko/20031007 Firebird/0.7. This is NOT a smooth scrolling problem. The web page described disables all ability to scroll over areas of flash animation only, smooth scrolling is still fully functional on other areas of the page described. This is common to both Firebird and Mozilla, although the filer of this bug should have filed this bug for Firebird. This bug should be renamed to "Scrolling is disabled over some flash animations"

I have been able to reproduce this problem now, but only with smooth scrolling, keyboard commands and scroll wheel are all working fine. I am going to confirm it, and have changed the summary to try to reflect what is going on, if it still seems unclear please fix it or offer better suggestions.
Status: UNCONFIRMED → NEW
Ever confirmed: true
Summary: Smooth scrolling completely disabled by page with lots of flash on it → Smooth scrolling will not work with flash animation in window

Can I just add, I see no evidence that the web page www.dafc.co.uk disables scrolling. The flash animations may do this, however, the effect is not evident with smooth scrolling disabled. Furthermore, moving the mouse over the flash animation while attempting to scroll does not cause this behaviour. I believe the problem is due to the very fast scrolling employed by the large flash animation at the top of the page. This is somehow preventing the smooth scroller from ever getting started. As far as a solution goes, coult it perhaps be arranged to "fall back" to non- smooth scrolling when this type of thing happens?

Is this still around in FireFOx 0.9.2 on Win and 0.9.1 on *nix? -R

I have also verifield that on http://www.wemake.pt/default.php same problem. If you have smooth scrolling CPU usage is maximized (60% to 86% computer time on my computer) out on this page as well - even when Firebird is minimized or not visible on the screen. Note: This Wemake page page uses Javascript (not Flash) Tigrascrooler [www.softcomplex.com/products/tigra_scrooler/] and so the problem must be on the smooth scroller function somewhere. It seems an Netscape heritage on because with Netscape 7.1 the resources are also (and a even little bit greater extent) consumed With Mozilla (version 12.00.8804) some behavior. I tried also in Linux with Mozzila 1.6 and it almost stop (and not with konqueror) so it must be a bug not a OS problem. Internet Explorer runs also Ok. So Gecko has a problem somewhere!

I had used Firefox 0.9.2 Note: summary must be corrected.

Obviously Internet Explorer works fine on this page also - scrolling works as expected. I believe the problem may lie with the fact that Mozilla/Firefox seem to redraw very slowly and jerkily compared to IE when there are flash elements on the page. It would be nice if this could be fixed before Firefox 1.0, but to be honest it is not preventing me from using Firefox as my primary browser both at home and work now.

I see a different problem in this bug when I browse with either mozilla or firefox. Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a5) Gecko/20041024 With smoothscroll enabled in Mozilla all scrolling is disabled (scrollbar, scroll wheel, keyboard) when I view the flash, (until I switch away from the window and come back again). Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.3) Gecko/20041026 Firefox/1.0RC1 In Firefox only smoothscrolling doesn't work when the flash is in the viewable part of the window, I can use all other scrollers. I'm not sure if there should be 2 seperate bugs filed, there probably should, but for now I'm sending this back to browser because the firefox specific problem is less severe, and browser is a more general place to put things. If anyone feels strongly about it they can either file a new bug or tell me I'm stupid.

testcase shows jerky smooth scrolling with linux trunk 2005032605 it's most noticable if you scroll down to the bottom of the page, and then scroll back up by holding the up arrow key.

Dupe of bug 202718?
Comment 24•17 years ago

http://www.wemake.pt/default.php maxes out my 2.8GHz Celeron. Firefox 2.0.0.5 stays responsive though. As i didn't see any play button (i'm using Flashblock 1.5.4), i'd say that's a DHTML perf bug. I get jerky scrolling and 100% CPU use while trying the testcase in comment 21. Kubuntu 7.04 and Flash 9.0 r48. Bug 202718 has a better description and blocks another bug, but this bug has a testcase and has OS: All. I'd integrate that bug with this one.

Andrew, sfw file http://www.dafc.co.uk/lightboard.swf in testcase redirects/not found, so I'm not sure your testcase is still valid bug URL stb no longer a problem. http://www.wemake.pt/default.php (a 100% pig) indeed would not be related.
