Hi Vishal,

Can you tell us more about what you're trying to do? It sounds like you're doing OAD?

Have you beeen able to replicate this with a newer version of the SDK? The 1.35 version is quite old and since we have improved OAD a lot. If you are using OAD, you could have a corrupted image.

Please try on 2.20
