Square corners on notifications

On my iPhone 12 I got since iOS 16 till today with iOS 17 randomly square corners for a second in my notifications. This is getting annoying. Someone else got this? Reddit is full of users with this bug. I hope someone can help. On reddit every user got this. No matter which device. From iphone se to iphone 14 pro max. Its really disappointing when I got a new message and the first look is a iOS Bug… doesnt look like a quality phone. Just like a cheap china android.
