What exactly is the difference between logicalSurface and logicalsurface.surface? in draw(), you draw directly on logicalSurface. But after that you blit logicalSurface.surface to the screen.
pygame draw functions will lock/unlock surface automagically IIRC, so the problem is likely with the blit call. Try to find out if either of the surfaces is locked, and if so, try to unlock them. The surface may be locked multiple times, and you must unlock it the same number of times to regain access, so you might need more than one unlock call. Are you locking these surfaces elsewhere in your code? There may be a bug in that code that causes some surfaces to stay locked when they shouldn't. Remember to call unlock the same amount of times you called lock. If you don't use lock in your code, there may be a bug in 1.8.0 locking.
