You are rotating the whole canvas when you use context.rotate, and since the pivot point is defaulted at the coordinates (0, 0), your square sometimes will be drawn out of bounds. By moving the pivot point to the middle of the square, you can then rotate it successfully. Note: Make sure you rotate the canvas before you draw the square.
