I've been having an issue with both these games. Skyward Sword isn't so bad but it may be related to the Red Steel 2 problem. Red Steel 2 objective screen keeps popping up randomly during gameplay, Skyward Sword, when dowsing or looking (Or just happens randomly) keeps shield bashing taking me out of dowsing. I don't move the nunchuk at all but it does it anyways. Sometimes it just does it while fighting. Sometimes twice in a row. But like I said it's not as bad as Red Steel 2 which just interrupts gameplay completely, which can happen right in the middle of slashing my sword. I can't find any information regarding this problem with either, but as far as I know it's an cios issue. It can't be the nunchuk cause I tried both mine and bought a new one and it still does it. No other games have this problem, just these 2.
