Chrome 17.0.963.46 – border bug

Screenshot demo.html

The newest version of Chrome (17.0.963.46) is a bit of a trouble maker – at least on Windows 7 x64. Seems like the border-radius property causes a bug, which fills the background of the element with its borders color – not entirely, but partly at a height of height x ~0,50-0,52.

Deactivating the border-radius seems to “fix” it, and scrolling has also some effects on it.

body{height: 1500px;}
background: #ccc;
border-bottom: 5px solid blue;
border-radius: 2px;
height: 300px;
width: 200px;

<div id="foo">

Same story on Windows XP x32.

The bug seems to be related to the width of the border and the border-radius. Changing these values produces even weirder display errors. If the border-radius is bigger than the border-width, the background isn’t affected anymore, instead a border-left/-right appears (demo4) up to the same height as the background earlier.

The combination of border-top and border-bottom produces a similar problem (demo5), the top border fills up the other part of the element. If the border-radius value is higher than the border-width, the same effect as above occurs (demo6).

The bug doesn’t appear, if a border-left/-right is added to the element.

In the meantime, I added my report to an existing issue #113368 on Google Code. Additionally, there’s another issue (#113726) report (thanks Dave). Since issue #113726 seems more active, I’d suggest to file future experiences there.

The update to 17.0.963.56 stable from Wednesday, Feb. 15th had no impact on this bug.

Since nobody seems to care about this bug at Google/Chromium, i had to figure out a workaround – quick and dirty. Not the best solution though, but at least the websites don’t look too fucked up:

[code lang=”javascript” title=”JavaScript Snippet”]
var browser = navigator.userAgent;
var buggyVersions = [‘Chrome/17.0.963.46’, ‘Chrome/17.0.963.56’, …];
for(var version in buggyVersions){
if(browser.indexOf(buggyVersions[version]) !== -1){
document.getElementsByTagName(‘html’)[0].className +=’ buggy-chrome’;

[code lang=”css” title=”CSS Snippet”]
.buggy-chrome .messedUpElement{
border-bottom-left-radius: 0 !important;
border-bottom-right-radius: 0 !important;

I just updated to Chrome 17.0.963.66 stable, still no bugfix.

Update 16.04.2012 08:55

Wow.. looks like in 18.0.1025.162 the bug has been fixed.
