Thanks, I wasn't sure which link I should post. I read the German version on heise: https://www.heise.de/hintergrund/Googles-Kamera-verfaelscht-.... But a German article doesn't really fit here. So I thought the original source might be good, didn't realize it was behind a Google login, since I was logged in already.
The camera app in Google Pixels running Android 12 tries to "fix" some URLs encoded QR codes, resulting in wrong URLs being shown and opened by the browser if the user clicks on the suggested link.
Here is a screenshot of the issue as of time of posting. Forgive the zoom, the UI has a iframe scroll which isn't very capture friendly. https://i.imgur.com/hS8jBzw.png
