The driver unconditionally sets xpanstep to 2. However, a value of 4 empirically works better at bpp = 8, and 2 for 16 and 32. This buglet was exposed by the rotation code. Second fix is the unconditional call to update_start() without verifying if the offsets are correct. Remove this call, it's not necessary and secondly, it causes a crash with invalid values.
