@MohamedRejeb Can you please create a minimal reproducible sample project on this problem and share it on GitHub?

Here's a minimal reproducible sample project:
https://github.com/MohamedRejeb/CMPIssue4380

It's happening only for macos, try to click: floating -> fullscreen -> floating and the placement will end up maximized instead of floating.
Also you can try fullscreen -> maximized and the fullscreen will exit correctly.
