First I would check if its really no JavaScript/GWT code that goes wild after a while. I think I would just start CPU profiling using Dev Tools and keep an eye on it until CPU usage increases.
Other than that you probably have more luck solving it by asking the Chrome guys. Btw its not surprising that it also happens in Opera because since Opera 15 the browser is based on Chrome's Blink + V8 engines. Try older versions of Chrome also. Maybe there is a version that does not have this problem. -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
