Something very unusual is happening on your device if it's behaving that way. Have you installed the latest firmware? One thing you can try doing is going bringing up the annotations editor with your finger, tap the three dots at the top right, then Settings, then uncheck "Stylus Mode". You will no longer get the fast writing with the pen tool, but if that feature is not working properly with your device, I'm not sure what else to suggest. If stylus mode is currently unchecked, then checking it is advised as you'll then get the very fast response while using the pen tool.
