RX590 Ui Lag Catalina 4K

Hello Friends;

I tried different system setups i9 9900k with Asus z390-e and now the system config like below. When i chose a resolution like 3008x1692 or bigger i get an laggy ui resizing windows getting slow, launchpad opens slow, i feel and see the mouse cursor is laggy etc. Since i tested on different cpu & mobo i think it is gpu related. Monitor works fine on windows.
