bug: Extra layout appearing on Information page
Btw Following the position of the image in the mouse in the world page requires a strange offset, I don't know how to fix it

const imgOffsetX = 350;
const imgOffsetY = 0;
const imgOffsetXPercentage = 75;
const imgOffsetYPercentage = 0;
const newPosition = {
  x: x - imgWidth / 2 + (imgOffsetX * imgOffsetXPercentage / 100),
  y: y - imgHeight / 2 + (imgOffsetY * imgOffsetYPercentage / 100)
};
