flat pano corrupt display in ios 7 (v1.18)

Could someone confirm that what I am seeing is correct? Flat panos displayed in ios 7 get distorted / corrupted tiles. I can only test this in iOS simulator but it happens both in Xcode 6 and 5. No problem with ios 8 in the simulators or physical devices nor ios 6 physical.

Here is a screen grab comparison iOS 7.1 (left) and 8.0:

You can check for yourself here: [url='']Flat Pano iOS test[/url]. As you zoom in and out you will find the image is solid and complete at certain zoom levels but but not others.

Klaus -- do we have a bug?

Thanks, Klaus. Good to know. And just to be absolutely certain, you tested my example on a physical device running iOS 7.x?

Great! That is most reassuring, although not so much for the accuracy of iOS simulator....
