Struggling to change the combobox mouseover effect on a dark background

Question

Hi, hope someone can help, I tried to follow some answers here but I am not able to change the ugly default mouse over effect on my combobox. I want to keep the same style as before hovering with the mouse. I am really struggling with it. Below my current code. Thanks a lot!!
