Help With Developer Menu In Web Browsers

I was wondering if anyone could explain what that possibly could be or mean. I have tried searching the internet, but can not find any information on it. It looks like this:

I think if the loaded page contains different elements (like images, flash,..); The browser requests each element separately. 'Paint' is constantly fired as soon as the requested element is received by the browser.

This behavior may be an indication of time-based execution of javascript, as done with setTimeout() or setInterval(). Most browsers will do repaint that's hard to predict even on small changes to the dom tree. If you have a URL for the page in question, we could sort out your browser issues from problems on the page itself.

It is due, to some plugins I am using. specifically jScrollPane, could be so high, due to other plugins.

It might be due to HTML5 with canvas elements constantly being repainted.
