Text is cutoff at the 45, 135, 225 and 315 degree positions

Due to the Zeblaze Thor 4 having a round screen, apps such as Gmail have text being cutoff at the 45, 135, 225 and 315 degree positions.  How do I get around this?  What buttons do I press in order to turn the screen from round to rectangular/square?  Thanks!
