I have a UITableView which only takes like 3/4 of the screen, but not the entire screen. Now I wonder if it matters to scrolling performance a lot, if outside the UITableView there are views with alpha 0.5?

When a table view scrolls, is the entire screen affected with compositing and drawing, or only the frame of the table view?
