New UI is unresponsive and Makes Game laggy/slower!

The New UI is very unresponsive and takes multiple clicks to activate. Additionally, the new UI takes up a lot of space than the previous UI, for some reason, this makes using the UI make the game slower and freeze more. Id recommend making the UI more simpler and smaller to reduce lag and make it responsive ( I say this becuase the old UI is small and all the buttons are responsive and small, making it easier to use your fingers)
