(From http://stackoverflow.com/questions/10534136/webkit-render-bug-for-dynamic-content) When I change the content of a span with javascript this change does not get rendered in Webkit browsers. This effect only applies when a wrapper span is positioned relative and the inner span is positioned absolute and has a fixed width and height. Here is the most simple example of the bug (check it in a webkit browser like Chrome or Safari) <!DOCTYPE HTML> <html> <head> <title>Webkit render bug</title> <style type="text/css"> .wrapper { position: relative; } #absolute-block { display: block; position: absolute; width: 152px; height:42px; background-color: #EEEE00; color: #FF0000; } </style> </head> <body> <h1>Webkit render bug</h1> <button onclick="document.getElementById('absolute-block').innerHTML = 'Update test';">Update test</button> <span class="wrapper"> Some content <span id="absolute-block">Absolute-block</span> </span> </body> </html> The click on the button will replace the content of the span in the DOM-tree but this doesn't get rendered by the webkit based browsers like Chrome and Safari. Other browsers do not have this render bug. Full FrameView invalidation fixes the issue.

This feels a little like the a left-over-anonymous block bug which Jullien and Ojan and I were discussing the other day. Where you change a block to an inline and then try to change it back to a block and it doesn't reflow on the right line.

Yup. It sounds a lot like bug 74976.

I can't reproduce this in recent nightly builds.
