Default [Q] changing DPI breaks camera

changed to 213 DPI on beanstalk 4.4.2. everything was great but camera totally dead as it would FC upon opening. Nothing would fix it, not even restoring another nandroid, even stock rom. Had to odin back to stock 4.1.2 and camera working ok again. Is this normal or how can the dpi be changed and not break the camera? Thanks.
