Possible regression in PySide 6.11 with WindowFlags Frameless and pyinstaller?

Today I received the PySide 6.11 update.

I’m developing a frameless application (setWindowFlags(Qt.WindowType.FramelessWindowHint | Qt.WindowType.Window)).

I’m building my application as an executable using PyInstaller 6.19.

Well, I now have a gray border that matches the border of a Windows window (Windows 11 in my case).

I reverted to PySide 6.10.2 and I no longer have the gray border issue on my application.

So, I’m talking about a PySide regression, but is it also possible that PyInstaller is bypassing an option in the build process and breaking the application’s appearance when it’s in executable form?

Thanks :slight_smile:
