Hover color errors | WordPress.org

How to disable the hover color link effect in the entire plugin? Mainly due to errors, e.g. revisit config icon, which is round, when you hover the mouse over it, a colored square is displayed instead of an icon, the same thing happens with the X button, so instead of changing the color as a button, the color is displayed in the form of a square, it looks tragic, and there is no option for this in the plugin itself. If there is an icon that has a given RGB color, after the hover action it should change to a different color, but there is an error.
