Hi Johann,
I am not sure what do you mean by "reloaded" - is it "fetched from remote location and re-rendered" or "redrawn and the layout changes or flickers"?
In either case, I can't imagine how the Spliter is involved and this seems like a browser-related bug. However, if you provide a runnable example, I will take a look.
