I have an element located at the top of the screen with a z-index of 100. When I view a page in Chrome (V. 21.0.1180.82 on OS X and V. 21.0.1180.83 m on Windows) I notice a rendering problem that looks like this :

UPDATE:
I noticed that a rendering problem occurs every time a fixed element skips a new <section>...</section> while scrolling. Chrome seems to have some issues with HTML5 tags, such as <section>...</section> or <nav>...</nav> . Changing these options to <div>...</div> solves the rendering problem, anyway, I would still like to continue using HTML5 tags.
Does anyone know a “hack” to solve this problem?
Until then, I will try to create a reproducible code sample and register a chromium error.
