I have a UI where the navigation is over a blurred set of images (blurred using webkit blur), and whenever the navigation moves, theres this strange almost ghosting effect that happens. After you click away onto another element, the ghosting also goes away.
Any advice on how to solve this?
On Mac Snow Leopard:
Chrome 19.0.1084.56
Safari all of them, including 6 beta
It seems that you are encountering a browser/engine dependent issue.
Chances are : you can't solve it by yourself aside from not using blur, or the like.
Not that this bug might not impact all users, depending on the version of the webkit they are using.
Hopefully the problem will be corrected in a future version. Maybe try to contact webkit guys, but that's really all you can do (aside submitting a patch).

I'm using rgba colors, but after switching to HEX the problem still persists. I never had this issue a few weeks ago, and just noticed it. All opacities on rgba colors are set to 1 (100%), so they should appear. I assume it's a new chrome bug?
The left screenshot is Safari where it works and the right is Chrome.

Same to me. I found a fix! Aparently there is a bug with webkit with the backface of a div element. This code will help
-webkit-backface-visibility: hidden;
You can found more info in w3schools.com -> here
Chrome appears to have some rendering bugs. Especially after GPU Driver Updates or Chrome Updates. A friend of mine had them for months.
You could try tuo update your drivers but theres no guarantee it helps.
Same happens to me. I tried to download Chrome beta. The weird rectangles do not appear there but the background color still does not act as it is supposed to. You can take a look at my page - the blue background color magically changes itself as soon as the whole landing page disappears.
for sometime now I'm experiencing some strange happenings (jumping/flicker) on firefox all around the web. When hovering an image which have some sort of css animations/transition (opacity,transform,...) the image jumps. Additionally it's also very random, so very hard to figure out and solve.
I wasn't able to find anything related to this issue on the web.
Are you also experiencing this, or am I the only one?
Here are some examples where I'm experiencing the described issue:
http://www.undsgn.com/uncode/works/portfolio-full-width-masonry/ (on mouse hover)
http://www.airliftcreative.com/ (on mouse hover)
http://oxfordhouse.nl/ (open the menu and hover the items)
Thanks for your help.
I had this similar issue happen to me when I was using an older instance of Firefox on my windows 7 machine. I updated it but, the problem persisted. The solution I found was to uninstall the browser entirely and reinstall the latest version.
If you need to backup your profile (bookmarks, passwords, etc.) I found the following support page helpful

Best of luck :D
I should start by saying I'm no expert when it comes to code and web design. That said, I have recently upgraded to OS X 10.9 Mavericks. After updating I'm experiencing a weird bug, specifically on my website and others like it using the wordpress theme WPfolio Two. When you hover over a link, the link jumps and drops to the next line. As soon as you move your mouse away from the linked text the text link hops back up to the line it's supposed to be on. This only happens using Chrome or Safari, it does not seem to happen in Firefox. For an example hover over any link on on either of these two pages http://jasonirla.com/category/news/ or http://notlaura.com/wpfolio-two/read-me/ Thie bug does not seem to effect drop down navigation menus or some (but not all) links in sidebar widget menus.
The bug makes it practically impossible to click the jumping link. I'm not experienced enough to say if this is a browser bug, a OS X bug, a problem with the code in the wordpress them I'm using or what. I am comfortable editing and writing small additions to the theme code using a child theme CSS but in this instance I have no idea where to start or what I'm looking for (to fix). All I know is that this problem did not occur when I was still running 10.8 mountain lion on my mac.
If anyone has any experience with problem like the one I'm experiencing and could offer me some advice I'd really appreciate any help you can offer. I've been searching all over for a week now and haven't been able to find any answers and nothing I've tried seems to make a difference. Thank you for any help or advice you are able to offer.
Can't leave a comment, so I hope this will help you:
Check your font-style on this hover link, is it bold on hover?
Do you use another font-size on hover?
Do you use a iOS compatible font on hover? (using a font that only works on windows systems will be transformed on iOS devices and could cause this bug.
I was contacted by the designer of the WP theme (WPfolio Two), there's a style on 193 of the CSS "display:compact" which is the problem. I put block comments around that line /* display:compact */ and the bug is fixed. Thanks for the initial help #lickmycode – user1544398 just now edit
Unfortunately I can't reproduce this in a JSFiddle or otherwise, when I do it simply works properly. From there I still was not able to narrow it down to figure out what is causing it. Here is the link to the development site:

This bug is only visible in Chrome, I am using the latest version, and the problem still appeared on the previous version (I just updated this morning).
Watch the links in the content of the home page carefully, when the image slider transitions, you will see a change in the text of the links. It's almost as if the anti-aliasing changes somehow and causes the text to become just a smidge thinner. You may need to zoom in to see it well.
Any idea what's causing this? I'm completely stumped, the only thing I can figure is something in the rendering of the animation of the slider is tweaking some anti-aliasing or something causing the fonts to move a bit. Even the youtube and linked in images in the footer have the same problem.
#content * {-webkit-backface-visibility: hidden;}
The above fixed it thanks to someone in Chat.

We've run into an optimization problem using WebKit on Mac OS X that we're hoping someone can help us with.
We've written a Cocoa app for Mac OS X that essentially manages a single WebView that points to our online web site. Everything is working fine for the most part. However our web site uses CSS's position:fixed to keep a thin "header bar" locked to the top of the WebView, similar to the big orange "Welcome" bar at the top of StackOverflow.com. We've determined that with position:fixed active, scrolling the WebView forces the entire web page to re-draw itself, which causes scrolling to be agonizingly slow. With position:fixed disabled, scrolling is very fast and fluid; only the page elements that are scrolled "into view" need to be drawn.
We know that this isn't a bug in our Cocoa app code, nor is it a problem with our HTML/CSS code. The same slow scrolling occurs using WebKit test code from Apple. We can point Apple's test code to http://www.StackOverflow.com as a test and we see the exact same behavior. There's also a test page in the Mozilla bug database that we've been using to test the problem (https://bug201307.bugzilla.mozilla.org/attachment.cgi?id=139911). The odd thing is that some WebKit-based browsers on the Mac (eg, Safari and Chrome) don't have this problem; scrolling is always fast on pages using CSS's position:fixed with those two browsers.
Has anyone else experienced this problem with WebKit on OS X? If so, what can we do to speed up our scrolling? Thanks.
I might be way off here as I'm not sure if the same will apply in your web view, but using a style that forces the nav onto its own layer may help.
Something like translateZ(0), or translate3d(0,0,0,). I've come across similar issues when building with Phonegap and applying some thought to layering really helped out.
I believe the browser can utilise hardware acceleration where a third dimension is involved.
I was having a similar problem: the fixed bar was flickering when I was scrolling the page.
So I forced the WebView to use layers and I fixed
[w setWantsLayer:YES];
I had a similar issue in my webview based mac app. It has header and footer with position:fixed css property. Latest webkit shipped with 10.10.x and above don't suffer from this issue. It happens in webkit for mavericks (10.9.x). I got it working by setting these properties for the webview
[self.webView setWantsLayer:YES];
[self.webView setCanDrawSubviewsIntoLayer:YES];
