Looks like either a screen protector (if one has been installed) is coming off or the lcd screen is de-laminating. If it's the latter, Tesla will need to replace the screen. If that needs to happen, make sure they replace the screen and don't just squish out the bubble and send you on your way. Sometimes such bubbles close to the edge of the screen can be fixed by squishing them out flat again. However, all that does is buy a little time.
