I have the same issue, even with the grid. Sometimes I think it is the camera...

Yeah, one wishes that they could afix the sensor better in the camera; such shoddy manufacturing! And then you take another shot, and the bouncing mirror jars it back into proper position. Odd thing is that a tripod mounted camera doesn't resolve the sensor position via the reflex mirror jarring, I guess it is because of the tripod dampening the vibration?! If you take the camera off the tripod and walk around with it, sometimes the sensor goes back into the right position by itself, I guess because of the vibration of walking around; but othertimes it jars into the out-of-kilter angle.
Some other folks have issues with the AF sensor moving, and throwing their AF out of kilter from time to time, and they think it is the AF microadjustment that fixes the problem.
