Hello Yano,

In order to fix the problem, please hide the overflow of the page - if scrollbars are needed, the splitter will generate them:

<style type="text/css">
       html, body, form
       {
           height: 100%;
           width: 100%;
           margin: 0;
           padding: 0;
           overflow:hidden;
       }
   </style>


On a side note, I also prepared the following notes which can help you improve the code further:

- Do not set any sizes to the nested splitters if they are directly nested in a RadPane  - when a RadSplitter is directly nested in a RadPane, it automatically resizes itself to occupy 100% of the parent pane. If you set width, height, fullscreenmode, the splitters will make a lot of calculations to resize themselves and this is not necessary and slows down the performance without any benefit.

- when you have a vertical RadSplitter, do not set the Height of the child RadPanes (the same for a horizontal splitter and width) due to the above explained performance consideration

I hope that my reply is helpful, let me know how it goes.

All the best,
