How to view both screens on Citra?

When i load any game, i can only view the bottom screen and it is shown as the top screen while the bottom half of the window is white. How can i view both screens at once?
As far as i know, if i change it to Single Screen i can view the top screen but i cannot view the bottom screen in exchange

this is an issue and not the intended citra’s behavior, try updating your gpu drivers
