Problems with Scrollable Container and text

Hello everyone :)

I've got some problems with the Scrollable Container. I created a small application based on the "Scrollable Container example". If I scroll the text, there are some issues. There is a delay between scrolling and the updated display of the text. It does not run smoothly.

It does not matter if I enable scrolling vertical, horizontal or both.

But on the other screen is a (horizontal) Scroll List with 12 Icons. There is no problem.

It works perfectly. If anyone has a hint for me....

Thank you very much
