See here for dozens of reports about a simple thing like window settings:

But hey,
Lets throw in a new ship that’ll fix things.
Did we get a new ship…?
I hope you do realize that you have not described the problem you might be having?
If i click on the search results with your link provided, then the first one is about KDE settings on Linux, the second one is about Windows on a multimonitor setup, the third one then is about a problem on MacOS, then Linux again.
Also most of the topics i looked at found a solution or fix.
I also can report that on Linux with a Wine and X11 based setup i have no problems with a fixed window, because there you can specify a virtual desktop from the outside and tinker with it until everything suits you.
I suppose this won’t help with your problem, but actually what problem and what system is it for you?
I also don’t know what exactly is his issue with window settings, but he is not wrong. CCP completely ignore bug reports. I even reported a highly abusable exploit 2 years ago, still not fixed lol.
