I am pulling my hair out on this one.
We're just about done with the development of an overhaul to our site. As a last step, we're trying to wrap up all the glyphs and icons into a sprite. They're all transparent .png's so the sprite is too. It appears that if a background comes from a sptire, IE distorts it. If it comes from the original file, it does not. FF and Chrome are fine either way.
I am looking at the orignal image and the sprited version side-by-side with grids to see that the pixels are identical. I have counted the pixels in the sprite many times to ensure I'm using the right coordinates. My CSS looks like this:
XXbackground: url(sprite.png) no-repeat 0px -837px; /* lozRedRedSpacer */
background: url(lozRedRedSpacer.png) no-repeat;
The 'XX' lets me toggle back and forth. With the single-file version, it looks perfect: . The sprite-version looks like this: . It looks like it is 'squished' both vertically and horizontally. This does not happen in FF or Chrome.
Any ideas?
EDIT I was able to strip out most of the noise and post an example here. I've added notes to the example to describe my problem.
Thank you so much for taking the time to look at this!
UPDATE We've since replaced these 'overlapped divider images' with CSS pseudo-classes that REALLY do overlap and the zooming issue seems to have gone away. Of course now we have new problems - IE8 gets the z-order wrong and IE7 doesn't understand psuedo-elements at all. But at least the markup is simpler and the zooming issue is gone.
It turns out my problem was caused by IE's 'zoom' feature. Without any zoom, everything looks great like the other browsers. Even 150% or 200% looks good. But 125%, where I had it, causes this distortion. It happens in IE7 and IE8.

Ok, see if you can help me out with this one:
1) Go here: http://thepredatorial.com/DHS/index.php in Google Chrome/Firefox/IE9
2) Everything looks great
3) Go to the same web address in IE8
4) There is a gray background (that matches the outer corners) behind the slides of the slideshow that I can't seem to find out why or get rid of...
Any help?
Ok, I ended up fixing it on my own.
Because IE8 had crazy bad PNG transparency issues, I ended up making a png of the entire block above and below the transparent gifs, absolutely positioning it ABOVE everything, then z-indexing everything BUT the banner slides above the absolutely positioned element.
Crude? Maybe. However, now it works beautifully in Firefox, Chrome, IE9, IE8, and FOR GOD KNOWS what reason IE7 as well.
IE8 and below has issues with applying transparent effects to already transparent images. It appears your jQuery "cycle" effect is causing this: remove the flashing transparency, remove the grey background.
Since IE's dev tools are fairly crappy I couldn't easily test any of the workarounds posed here on your actual site, but hopefully one works for you: Problem with JQuery cycle on IE8
I have a mysterious (at least for me) css background image problem, that I run into only with Google Chrome. I have found similar topics, but unlike those, here no Javascript, JQuery or anything else is involved, it is pure CSS. It's just not working as it should.
If you open up the page www.bodrogietterem.hu, the background image should be below the entire content area (as it is in other browsers). In Chrome a horizontal and vertical white area is appearing.
Once you start scrolling, the background image appears all okay, and it stays there from then on. Similarly, when you open the dev tool with inspect element, the background image is immediately there, and stays there, too.
this is the pertaining css:
body.page-node-1 div#main{
background:#FFFFFF url('/sites/all/themes/bodrogietterem/images/bodrogi_bodrogi.jpg') bottom;
background-repeat:no-repeat;
background-attachment:fixed;
background-position:50% 135px;
padding-bottom:0px;
margin-bottom:0px;
}
and attaching two screengrabs on how it looks like, and how it should look like (well, I'm not allowed to attach these, as a new user, but have a look here:
http://www.bodrogietterem.hu/chrome_issue.JPG
and here
http://www.bodrogietterem.hu/should_look_like.JPG
It happens on sub-pages, too, but I think the root of the problem must be the same.
I'm using Vista, with up to date Chrome (20.0.1132.57), and up to date other browsers. btw, the second screenshot was taken in Chrome, too, but after opening the dev tool
many thanks for your kind help,
bests,

The latest version of Chrome is 21.0... so try updating chrome browser and see if it appears ok in the latest version. The screenshots lead to a 404 error page, so try uploading the screenshots again.
I also checked the page in IE7, IE8, IE9 the page looks good in all 3, IE7 however shows a horizontal scrollbar at bottom but the background image looks ok.
Your page looks fine in Chrome in windows 7 (Chrome 20.0.1132.57)
I have had problems in the past where various toolbars / addons that have been installed interfere with the CSS on a page quite significantly rendering Chrome to appear to bug out in isolated incidents. Try running chrome with no addons / plgins installed and see if it fixes your problem.
One observation on your CSS: #content contains floated elements that aren't cleared. I dont think that's the problem here but could be mixed with the above possibly.
Let me know if that helps at all.
Thanks for your helpful thoughts, I finally managed to resolve the problem.
While fiddling around, I measured the height of the white area, and it turned out to be 135px (which is exactly the top position of the background in the CSS above). So I decided that for whatever reason, that attribute was causing the problem, and I was right.
as a quick and dirty solution, I added 135px of white area to the top of the background image, and set the background-position property's top to 0px - which immediately fixed the issue.
as for the vertical white area, it was resolved by binding the background image to the #main-wrapper div instead of the #main div (it is a Drupal 7 build). Again, I don't exactly know why, but it fixed the problem instantly.
I love, how the web should be precise and logical, and it still stays random and ad hoc at times
thanks again for your time and effort, bests,

Had the same problem with two pages of http://www.stoerbeton.nl but I think I solved it after reading your above posts and some thinking.
The problem was probably in the general background: url; attribute and loading of the website css. I replaced all general background: #222222 url repeat etc.; for background-image:; , background-repeat:; and background-color:; etc.
Please let me know if your website works after editing your css. I'm still testing.

I'm having some trouble with the CSS in my site, both with image sprites and IE compatibility.
Here is a jsfiddle: http://jsfiddle.net/lipestyle/EjQTP/7/
The two main problems are:
In IE, the contact links at the bottom are not appearing in the blue bar, but way down and to the right of the rest of the site.
The image sprites for MMA Cage Door and FightNight Nutrition are not working. It appears that the hover image is on constant display, as the non-hovered image is supposed to be much lighter than what we are looking at.
On a side note - For some reason the background image repeating isn't working in the jsfiddle, but I haven't noticed a problem with it outside of that.
Any advice that you all can offer would be greatly appreciated.
Thank you.
EDIT
One other thing I am noticing with the sprites. It appears when I hover over an image the first image doesn't disappear, it still remains while the hover image appears on top of it. Is that how it is supposed to work? Because my images are semi-transparent, this is something I would like to avoid if possible.
Here is a link to the site in action: http://bit.ly/h1OXQA
Could be a width, margin-left, or even position relative/absolute giving problems here. I have not checked in depth through all css code to see the cause. A fast/dirty fix, obviously loading alternative css or html for IE7, is that setting (in IE7) the UL #social with top:190px and left:100px , it seems to fit ok (or fine tune to the preferred position) .I'd go from here to guess what is causing to act differently.
Seems you already fixed, images seen light when not hovered, darker when hovered. All in IE7.
Here is the test site:
http://www.bodwell.edu/summer/new_busp_11/
It looks totally fine in any browser, except of course IE.
The menu bar and title png graphics are getting cut off right at where the underlying layer is. I have no idea how to resolve this and still keep this looking as it is in the rest of the browsers, i.e. Firefox, Chrome, Safari, etc.
Help!
If you remove the opacity attribute it will work. (the one below) from the main_panel class
filter: alpha(opacity=90);
In the meantime you can do that (perhaps have an IE specific CSS that will remove that filter).
They look similar enough in my monitor.
You could use that yellow background image with a PNG transparency and not have that tag.
I'm unsure why IE is doing that though.
I just downloaded the IE8 full release so I could test a site I just created.
[Example Deleted]
Focus on the left sidebar background image. It is suppose to be a 1x1 semi-transparent .png image that repeats. IE8 renders it as a gradient!!! It get's even wonkier when you try to scroll your window or mouse-over the sidebar.
I had already tested this site in the normal browsers (IE7, Firefox, and Chrome). It looks exactly as I designed it in these. IE8 is FUBARed though. I tried to set IE8 to "IE7" mode but it still looks crappy. IE 8 in IE7 mode obviously isn't rendering the same way as the real IE7. Not even the "IE7 meta tag" works.
Has anyone else had problems like this? I thought IE8 was supposed to be a an improvement, not a step backwards.
P.S. Please excuse the crappy markup on this page. I used IE's "save entire page" feature.
It may be a rendering error in IE8, or perhaps it's some function to smooth the edges of repeated images that gives you an unexpected result. Either way it's not very surprising that you get problems using such a small image. Do you realize that the browser has to draw the image 190152 times to render the page?
I am using a 10x10 semi transparent png as background for a div in a page, and it renders just fine in IE8.
I fixed the bug and it isn't the gamma issue that is mentioned in that other post. My issue was being caused by the fact that the image is 1x1 pixel in size. I just changed it to 1x2 and it fixed the problem. Weird
[edit] Just saw Guffa's post after i asked this. See his for answer.
I had a similar issue with a site I'm building. The issue only occurred on 50% of the machines with ie8 it was tested on, I was building it for an IT firm so had access to lots of computers. We were able to "fix" the problem by toggling Hardware Acceleration on the problem machines, not that thats really a fix at all.
Thanks for the help on this issue -- what a weird bug.
I was also experiencing the issue on 50% of the computers running IE8 (had access to quite a few machines). When I had a 1x1px semi-transparent png set as a background image on a div with CSS, IE would render this as a funky vertical, transparent gradient.
Changing the source image to a 5x5px png of the same opacity fixed the bug... go IE!
The problem was my original png was
1×1, and for whatever reason IE8 was
not liking trying to tile that and
handle the alpha transparency at the
same time. When I accidentally saved
that image with a much larger copy I
had on my clipboard, 100×100, it ended
up fixing whatever problem Internet
Explorer was having with processing
the png’s transparency.
