Secret Word Gardens

I have been playing Secret Word Gardens. I am happy that I am at Level 13 now. But there has been a problem. When I finish a game, I click on Play and my ink goes so I can start, but then the screen goes grey and then white with a icon on the top left corner. The icon looks like a sad square face.  This also happens when I click Return and the screen looks blurry all the time for a second then does the same thing I mentioned. This does not happen all the time, but does happen more than once. I don't know if I loose ink when this happens.  Does this happened to anyone else?  I hope there can be a fix to this.
