Hi! Just a heads up, this seems to be a problem in the Win11 21H2 update, as even with win32 APIs, the result is the same. It seems to be "fixed" (they just introduced a better API) in 22H2.

Thank you for your comment. I'm aware of that. My plan for 21H2 is an option to build a custom taskbar. Sadly, I can't make further developments till the end of the year. Yet, any pull requests are welcome.

My plan is to PR the native targets support once compose officially comes out with native support. I'll see if I can do custom taskbars as well.
