Would need to provide details on what you are referring to by glitchy.

Instead of just doing a Restart, it would be recommended to do a Force Restart to clean additional caches and perform some housekeeping.

Press and quickly release Volume up
Press and quickly release Volume down
Press and HOLD Side button until the Apple logo appears. This may take up to 15 seconds while holding the side button and you have to ignore anything else on the screen until you see the Apple logo, including the prompt to Slide to Power Off. If you slide to power off at that prompt, you have not performed the Force Restart.

I would only add that if you don't see the Apple logo after the last step of holding the side button, try again. It may take a couple of attempts to get the speed of the key presses correct.

Do I press all buttons at the same time?
