site page navigation slow, clunky, unresponsive

Okay, let me explain, pages load just as quick as ever, I'm not complaining about page load times. But for some reason when I attempt to scroll the page it's very unresponsive and clunky, like if I'm in a forum and scrolling down the comments, like it won't move much when I scroll or when it does it goes way too far, and not in a smooth fashion either. I know it's not my browser or computer (as least don't think so), every other webpage I visit doesn't have this issue, just GameSpot and it's been this way for a the past few days. There appears to be a considerable amount of lag when I want to scroll down a page and when it actually responds.

Are you on a mobile phone or maybe a tablet when you are using this site? It takes a very long time to navigate this site on my phone.

That is really weird.. I get that same issue on my phone, but the site works perfectly fine on my PC.

Try disabling all the addons in your browser and see what happens.

@super600: no, not on my phone, on my laptop

@lamprey263: Can you post your browser and OS information and wether or not you have any extensions running?

@alexisgallisa: I'm using Windows 8.1, running Google Chrome, only add-on I'm using is Ad Block which I've always used, disabled that and attempted to see if it'd change anything and it didn't. It seems to matter more when viewing pages full of comments and less so on pages that don't. But, I've viewed plenty of pages of equal content from other sites and it's not giving me the same kind of trouble.

Normally page viewing in other sites is only unresponsive if the webpage is loading some page content. It's behaving the same way here, only difference is it's unresponsive and yet the page is entirely loaded up.

I guess a solution should be to limit forum page viewing to 20 comments a page instead of 50. Though I wasn't having this issue last week or the months prior. Something changed about the same time my notifications started popping back up and that's when I noticed that scrolling the page became a painstaking task.

It's always been that way for me, ever since 'The Change'...

... and my notifications have yet to be fixed. :|

Kubuntu 12.04_64 - Firefox 26.0

well, for like two weeks I was getting none, I'm getting them again but it appears to fail at least half the time

@lamprey263: Hmmm I'll loook to see if anything changed in the forums styles which would cause the paint performance to get hit so badly for you. Could you give me some machine specs as well? Processor, Ram, Video Card.

@s_h_a_d_o: Same for you. Machine specs? Also is that latest version of Firefox available for Kubuntu? We are going to be making some simplifications to our css for versions of Firefox under 28 soon (there was a pretty big change from 27 to 28). It should be transparent and hopefully you won't notice anything (but maybe it will be a benefit).

Latest version of Firefox available (ex Mozilla) is 30.0, but 26.0 is all that's available on this system - that said, similar poor performance has been exhibited on my home PC's (under Win7 and various flavours of Fedora, all with the latest versions of Firefox) - will have to update with specs for those at a later juncture.

Got it. Thanks for the info. We may have found the issue. I'll post back in here when we roll out the patch and see if it helps.

@lamprey263: @s_h_a_d_o: we just rolled out a quick patch to address some of the layout thrashing which was occurring on scroll. We've got some more work to be done on it but we think we killed a pretty significant spike on that event. Let me know if it helps. We'll keep working on it.

@alexisgallisa: yeah, that seems to help a great bunch, thanks so much
