I cannot re-create this issue in any of my browsers, on any of my different connections.

Please post your computer specifications, operating system, website browser, website browser extensions, and running processes. Maybe even tell us how much processor and memory usage is available/free.

I cannot reproduce this. My computer is two years old as of last month so it isn't state of the art. The HTML is lighter than previously however we cannot ensure that all computers will be able to scroll smoothly.

Please check this thread out... I'm not alone with this issue.

My computer does the same thing for me. I am using IE8 and System7. I have a brand new machine used to game design so its not because my computer is cheap or old.

It happens when I use the scrollbars or the mouse wheel.

I've seen similar issues with IE8 on all sorts of sites, not just VB4 based ones. I'd say this is a browser issue.

Try some other browsers - Firefox / Safari etc. And see what it's like with those.

I'm using the latest Firefox... should VB not work correctly with Firefox?

Yes, I'm also using firefox and it works perfectly on both of my machines. What's the spec of your machine?

Also, have you checked background processes for malware / upgraded mouse driver (for scroll functionality). Does the same happen when you page up and down through the content, or only using scroll wheel?

sorry can not reproduce this.

Vbulletin 3.8 = No scrolling issues
Vbulletin 4 = Scrolling issues

You can ask which browser I'm using or what my computer specs are but the bottom line is I had no problems with previous versions of vbulletin. Also, others have this issue in the thread I posted above.

I'm done with this ticket.

Okay that may well be true - but it still helps the guys who develop the software to know what kind of conditions people are running the software under. Makes some kind of sense doesn't it?

If someone came to me and told me they had installed Windows 7 and it runs slowly, but they previously had Windows 98 and it worked fine - i'd still ask for specs of the PC. This is a new version of the software and while I agree that you shouldn't have performance issues any more than you had before, perhaps you can help other people to help you by answering the questions they ask (instead of getting arsey about it all)

Arsey? The only person who gets "arsey" here is the one disrespecting those who are trying to help.

Had you bothered to look in the thread posted above, you'd see that there are very concrete examples (along with links to other websites) for what is very likely to cause the behavior described in this bug. Now it's up to vBulletin developers to respond to the new information (so far they haven't).

Then doesn't it also make sense to provide information surrounding the issue? Such as... oh, I don't know... machine specs, OS version, browser version etc?

It's support 101 - if you have an issue, you post as much information as possible in order to resolve the issue, so that the people who are trying to help can offer some suggestions or the developers can use that information to possibly recreate the environment.

Are you affiliated with vB Solutions? I am asking because you speak in that authoritive voice that seems to indicate such. Otherwise I really don't understand why you don't let a developer of vBulletin handle this issue!

I hate to repeat myself, but for you I do it anyway: go to that thread linked further above and you will find *very specific* information discovered long time ago by others that shows how Mozilla- as well as Gecko-based browsers (Mozilla more so, though) have a negative influence on CPU usage when a layout uses the experimental CSS3 shadow property (which shows in particular when scrolling a page on slower computers). And also for your information: the current vb4 style makes heavy use of that experimental shadow property, and the more sections in your forumhome or the more posts on a showthread page, the worse the performance penalty.

Lol.... I like you. You're feisty. Can't we just kiss and make up?

:)

Let's skip the kissing part, but making up sounds good. :)

Nice one fella. You realise what will happen, is I'll get this problem when my forum goes live...

:) Have a good one!

I personally can't reproduce this, but based on the number of users reporting this issue, I'm going to reopen this so potential problems regarding the drop shadow CSS can be investigated.

I can't reproduce this either.

However, I highly doubt it is caused by the drop shadows, considering people are also reporting issues using IE8, which doesn't support the CSS drop shadow properties.

I can reproduce this and it is caused by the drop shadows and rounded borders. They come at a cost in Gecko/Windows, just like fixed positioning.
