When I customize the story size of storyline file previously made in 720x405 story size to 1600x900, (particularly for a quiz) it causes excessive flickering of the selected rectangle when the mouse is hovered on the choice. Also when the mouse is hovered on the answer choice text the selected rectangle zooms in slightly & shifts its position along with text inside towards radio button on its left. Both flickering of the first answer choice and shifting of choices in the rest invokes a sense of distraction & compromises user experience. Kindly suggest a workaround . I am attaching a video for better understanding.
