Are you using volume viewports and volume rendering or simply render images?

@sedghi Only render images. Can you please help me ? It is a extremely serious problem in production and a lot of our users are affected by this problem. Thank you very much.

Can you test again with latest iOS?

I created this PR which would be good enough for a lot of use cases (except the PT Scaled data)

@sedghi Thank you very much. I have tested again using latest cornerstone3D with latest iOS. It is better, but the refresh problem still exist. More than 300 dicom image files would trigger the page refresh before. Now more than 600 dicom image files would trigger the page refresh.

Can cornerstone add disk cache instead of only memory cache so that memory is no longer an issue? Large image series is very common in real world application. Thank you.
