Image rendering on Emulator is problematic

[Koichi_Tsuji]

Can not remember when it started to happen exactly, but the emulator on App Editor is quite volunable to render images. It is highly likely some of the images are broken. Then we open the app with the full screen, the issue is gone.
Emulator currently not working properly as "perview’ of the app.
Not sure if this is happening only to me and us.

See samples.
