Cascada has 4 calls of drawRotatedBitmap, but none of them seem to have changed behaviour.
You Cannot Go Back's call which enables playing the game when holding the PD in portrait orientation is affected however by the change.
Where the x offset in this line YouCannotGoBack/playdate/src/game.c at master · timboe/YouCannotGoBack · GitHub needs to change from -56 to 184 in order to move the rotated bitmap back onto the screen.
I can certainly provide fixed builds which work correctly from 2.7.5, but I will hold off a bit from pushing updates here - as this could potentially be affecting a reasonable fraction of the current PD content library. It would be good to know how confident we are that the bugfix will not be reverted due to backwards compatibility issues (cc @dave).
