title: How to minimize visual flickering with iOS8 "UIVisualEffectView with Blur"
body: <p>I have a particular app that, because of the navigation structure, leaves me unable to use normal UINavigationBars with translucency, so I've chosen to try and use iOS8's UIVisualEffectView with Blur.</p>
  
  <p>This solution mostly works, but there is a very noticeable flickering effect that occurs when the UITableView beneath this blur view is scrolled around. As the edges of an image or colored rect pass underneath the blur view, there is a significant amount of flickering that occurs.</p>
  
  <p>Has anyone experienced this? Anyone know how to solve this problem? </p>
  
  <p>My implementation is simple, I dragged a UIVisualEffectView onto my view controller and constrained it to top, left, and right screen bounds, and added a height constraint of 64. Beneath that is just a UITableView with some images and text.</p>
