I have the same issue. I started another thread yesterday as I did not see your thread until today. I apologize for the duplicate report.
I was able to find a temporary workaround for the star blurred screen issue. When you first open the game wait for the star selection tome to pop up. Once the star selection tome has popped up, do not select any stars, instead select your player name/avatar. At this point select the gear icon and logout then log back into the game. You should be able to play the game from this point; however, note that once you close the game application and reopen the app, you will have to take the same steps each time (log out then log back in) you reopen the app (at least until the bug is fixed).
Edit: I removed the initial time aspect about having to select the player name before the star selection tome popped up. As long as you do not select any stars and instead select your player name you will be able to complete the steps above.
