Hidden Window Creation

[FRex]

It could be added to the Styles flags.

Creating a window and instantly hiding it causes it to flicker on Windows 10 at least (very visibly and jarringly) on the screen so it's not enough.

The only previous thing I could find was this issue but it seem to not have been followed up on: https://github.com/SFML/SFML/issues/1155

And what's the use case?

It causes a very jarring flicker of the original Window on Windows if I want to do something with the Window myself right after creating it (like maximize or hide it). It looks horrible, bad on the eyes and look like a bug when it happens.

I have needed this in the past, and ended up adding it to my local version of SFML.

It was a while ago, so I can't remember the exact use case. IIRC it was something to do with loading resources before the window opened causing issues because of some openGL stuff I don't understand.


From memory, the windows implementation was very straightforward, especially if you're familiar with windows API, so if there's no complications on other platforms I'd fully support this request.

Laurent has already said that he wants pretty much this to be implemented as part of 'Window States': https://en.sfml-dev.org/forums/index.php?topic=23578.msg161405#msg161405
