Histoire de bug

Hello, I changed my phone almost a month ago, I have a Xiaomi Note 12. When I want to post a story or repost a post or a story, when I add an emoji, text, patterns, etc., my story posts with green lines. Once I wanted to change my profile picture and it showed green lines too, whereas with my old phone it didn't do that. I've talked to people around me and it's only happened to me... It really bothers me because I don't know where the problem comes from and why it's happening to me... Instagram stories are my whole life, so it's very disabling... I made 2 problem reports on Instagram but it hasn't changed anything..

I would like to know if anyone had or has the same problem as me and if anyone knows how to fix this please? Thank you in advance ❤️

Here is the problem:
