No. The windshield should clear the gas cap when opening. Your wood screws holding the windshield at the top are coming loose from the windshield header.
Your wooden header may be getting soft, or just the screw holes. See if you can tighten the screws a bit to pull it back up. If not, take one screw out at time and put toothpicks in the open hole and replace the screw. Sometimes this works if your header isn't too soft or rottenj. Good luck.
