Scroll wheel effect on dashed borders

[pardicity3]

I have always noticed this, and just accepted that it happens, but now I have become very interested in it.

When I use my mouse wheel to scroll down a page that has dashed borders on it, the borders get messed up. They get so that they aren't spaced out evenly or that they are just flat out straight lines. I don't know what does this, and I am not even looking for a solution so much as an explanation.

I figure it has something to do with the browser rendering the borders on the fly perhaps?

The page was probably rendered with an error on it. :p

Which browser(s)?

I've witnessed this with IE6 and my mouse scroller.
Never actually became solid, just dash sizes got a little different.

@zoobie - no, the page has no errors and validates fine.

@cg9com - yeah, I am using IE6. I have checked in other browsers, but I have only seen this happen in IE6/win. I also have definetely seen them go solid. Have you found anything on this?

I think it's just the way Windows uses your memory. I used to get that all the time using windows IE5, but now I've changed to Linux, such things as that, low memory alerts, pages acting weird which use javascript, etc etc are now extinct, and I'm using 1/2 gig of memory too

Hmm, that's a probably solution. I don't doubt you, but I do have 384 memory and I am on win2k which is supposed to manage memory quite well. Despite that I still feel like you are probably right Nightfire.

Actually I would suspect the problem has more to do with the video driver than anything else. I'd guess that you've got a buggy video driver and these changes are artifacts caused by the bug(s). I'd look for a newer driver for your card to see if that makes a difference.

@Roy - hmm quite possible, and that would mean this post is in the wrong forum!! :). Anyway, the only problem I have with that solution is the fact that this doesn't happen when I am using Moz or Opera or NS, only IE. Oh well, it's not a terribley big deal, I was just wondering if it was commen or not.

Hrm.. It could be memory related, but I doubt it. I'm using an old P2 MMX system with only 64mb ram and the only time I had that happen was in IE 5.0 but the borders just became unevenly spaced, not solid.. doesn't happen anymore, not in ie 5 or 6 nor O7, moz or konq. Still using the same amount of memory and I never actually have more than 10% free so it can't be.

Maybe a bit of an oddity, but the same happens to me with IE 5.5, but only when the border is 1px wide. Over that, borders are fine. (Doesn't happen to horizontal borders whatever the size.)

That you see an effect in one program but not another isn't a good indicator. The bug may only be triggered when things are done in a specific order or perhaps when specific features are used. Different applications may do things very differently. More specifically, IE will probably be trying to use things in the driver that are Windows specific while both NS and Opera will be performing the equivalent actions internally since those applications are designed to be portable across multiple OSes.
