Pull refresh demo shows black square

[realjax]

Well, like the title says. The demo online (http://dev.sencha.com/deploy/touch/e...s/pullrefresh/) shows a black square when pulled down instead of some arrow image. 's probabaly not right...

Edit: when viewed in Chrome that is.

Looks fine on my Chrome browser. Look at dev tools to see if it's not applying the css.

When it says "Release to refresh..." there is a black box, when it says "Pull down to refresh..." there is the arrow. At least in my case

I use Google Chrome 10.0.648.204

Guess it is a Chrome 10 bug because Chrome 11 is fine...

The only 11 version I could find was the beta.

But in my 11.0.696.43 beta version there's the same square block...

Screencast taken using Chrome 11.0.696.43 beta on Mac OS X 10.6.7

Notice I did refresh the browser before interacting with the List.

I got Chrome 11.0.696.50 Beta on Windows and it also shows the black square.
I think the alpha-channel is messed up in chrome.

May it works on chrome on mac.

Since it works on Safari and Android-Browser it should be a Chrome bug and not a Sencha-Touch bug.

edit: i guess its this chrome issue: http://code.google.com/p/chromium/is...etail?id=66372
a workaround is to embed the image as background instead as alpha-mask.

change the following lines in sencha-touch.css (line 4218 in debug.css):
.x-list-pullrefresh-arrow{
width:2.5em;
height:4.5em;
-webkit-mask:center center url('data:image/png;base64,iVBORw0..... no-repeat;
-webkit-mask-size:2em 3em;
-webkit-transform:rotate(0deg);
background-color:#111
}

to

.x-list-pullrefresh-arrow{
width:2.5em;
height:4.5em;
background:center center url('data:image/png;base64,iVBORw0..... no-repeat;
-webkit-transform:rotate(0deg);
}

I have Chrome 11 beta on Mac and it works may not be 100% of the problem.

I have Chrome 11 beta on Win and it doesn't work. maybe there is a difference between chrome on win and chrome on mac...

my workaround should work on all devices i guess.

It shows the same faulty behaviour in a webview activity @ Android 3.1 which afaik is webkit, not chrome..
