From my understanding that seems to be dependent on the theme u are using. The one with the squared icons is the htc black theme while the more rounded keys is the windows classic blue theme or whatever. Back when i first flashed to mightyrom full force (im on stock 6.1 now) it had the htc black theme set so the keys were squared when i changed themes they switched to the round ones and in some of the older themes that i made back in the wm5 days there are no shape for the keys at all (they just blended into the bottom bar) so try changing themes goto start-settings-personal-home or today then select a different theme.
