Blue rectangle surrounding the options located in the bottom bar in various apps

Hi Apple,

I have an iPhone 12 which is working absolutely perfect but there’s one minor glitch that is bothering me so much. For a few weeks I have been noticing a blue box around the options located in the bottom bar that we have in apps like photos, Apple Music, Phone, etc.Every app that has that bottom bar shows this glitch. I am not facing any issues but still it bothers me a little. What can be the solution for this problem?

These are the screenshots of some of the apps that show this glitch.
