Description
When running my application on my MacBook Air M4 (macOS 15.5), I get frequent messages from what appears to be macOS ind the terminal window:

I have not been able to determine what triggers these messages, but my best guess is GUI interactions.
There is no crash or unexpected behavior from the application.
The issue does not occur on my M2 M3 iMac, but this runs a (slightly) earlier version of macOS. Will add the version information when I get it.
Edit: Configuration of the Mac where this still works:
- M3 iMac (not M2, sorry), Sequoia 15.3.2.
