Viewport selection render doesnt work on dr?

Viewport selection render doesnt work on dr? When i use the viewport selection render and dr at the same time i get very dark stripes, is it a known behavior?

(i have a render but i want to add something more to it, so i add the things and select them in viewport, then select the option to render just that objects, and when i render the image the stipes begin to show)
