As _WINE_HWND_STYLE and _WINE_HWND_EXSTYLE respectively.
Gamescope parses these to make smarter decisions about what window to primary focus, or to treat as a dropdown/overlay.
This was originally a Proton commit by Remi Bernon, however, it would definitely be nice to have support for Gamescope focusing correctly under upstream Wine as well.
Fixes a bunch of games/launchers run with Wine under Gamescope.

I imagine there may be some concerns about exposing something that is specific to Gamescope, etc, but really this is an officially supported mechanism of Gamescope for it to make smarter windowing decisions that are simply not possible to express with X11 and the standard ICCCM properties.
It would be really nice if certain games and launchers worked correctly under regular Wine as well as Proton.

Gamescope is a very different type of compositor/WM compared to the others -- It is single window (+ dropdown) designed for a handheld/couch-type experience. We need more information than typical compositors/WMs to make informed decisions because of this.

Thinking of `winewayland.drv` as well going forward: I think we would probably want some private Gamescope protocol to expose similar information. I would say xdg-shell stuff is even more limiting. :sweat_smile:
If these are intended to be Gamescope properties, and at least in theory usable by non-Wine clients, I imagine we'd like them to use some prefix other than "_WINE_".

I would prefer to keep the name, but I don't really have a strong opinion.
It is really Wine-specific, unless there's another Windows translation layer about. I certainly wouldn't encourage typical desktop clients/games to start using Win32 window styles at all... :frog:
It just means more churn on the Gamescope side to support this under a new name. We'd have to support both of these names in perpetuity then to support older versions of Proton.
If we were to give it a new name, do you have any suggestions?
Not a maintainer, so feel free to disregard: would it make sense to merge all Wine-specific window flags into a single property, so that we can extend it (due to e.g., Gamescope needs) in the future without occupying more atoms?

`_WINE_HWND_STYLE` and `_WINE_HWND_EXSTYLE` are fine.
I think `_WIN_HWND_(EX)STYLE` and `_WIN_HWND_(EX)STYLE` are valid alternatives too.

Well, this has compatibility implication for long term.
If everything is put into one atom, window/display managers will have a hard time to adapt to the atom changes.
I think exposing the two Win32 window attributes, as two pristine, and separate, X11 properties, is the straightforward thing to do. Trying to define something specific is only making things more complicated.
Regarding the properties names, I think this is not some WM-specific behavior that Wine is implementing, but the opposite. We don't generally implement WM-specific behavior, and I believe we even try very hard not to, so if it were some Gamescope feature that Wine would have to implement I think it would not be acceptable.
However, I think we can consider exposing more Wine internal information to the outside world, in case other tools want to adapt their behavior to Wine. This is not always desirable, and I understand that we may prefer not to, for instance as debugging Wine-aware applications can be more complicated when comparing with native behavior, but in this case I think it can be justified and should be considered.
I'm going to approve it to show some support, as this would make upstream Wine (not just Proton) work better with Gamescope, and as it could allow other WM interested to improve their behavior according to these flags. Then I'm probably not the only person you need to convince here.
This merge request was approved by Rémi Bernon.
To properly reflect style changes this should be done somewhere like `set_style_hints()`.
