[Feature Request] Support Wine's native wayland driver

[KyunLFA]

Not sure if Wine bug or a Gamescope bug.

Wine's wayland driver works correctly, but not under gamescope by using the flag --expose-wayland

Forcing a new enough (or patched) wine to use (non x)wayland with "wine reg.exe add HKCU\\Software\\Wine\\Drivers /v Graphics /d wayland" (does not need to unset DISPLAY in this way) makes it so launching under gamescope --expose-wayland -- wine (insert program) cannot produce a viable window with the following logs:

For notepad or gamescope --expose-wayland --debug-layers --debug-focus --debug-events -- wine notepad :

Setting WAYLAND_DISPLAY and/or DISPLAY on the right side of gamescope command to various strings including blank, wayland-0 and gamescope-0 does not help like it does to Firefox for example (#808). Foregoing --expose-wayland doesn't help either as, as stated above, with this registry edit wine will ONLY use native wayland, which rules out the DISPLAY="" requirement and associated interfecences with gamescope.

I have observed the same behavior from at least one other user, and I'm waiting on a second. A quick and dirty way to get access to a precompiled wine with wayland driver ability if your distro does not offer it is to grab one of the binaries over at Tk-Glitch's wine-tkg avaiable for a variety of distros: link

gamescope: git master (dc81258)
wine: 9.0.r2.ge045af48 ( TkG Staging Esync Fsync )
wm: sway 1.9-dev-ae33f4eb
mesa: 24.1.0-devel (git-c3a64f8dd1)
kernel: 6.7.1 (CachyOS)

wayland_process_init Wayland compositor doesn't support wl_subcompositor

hmmm looks like wine is complaining that gamescope doesn’t implement wl_subcompositor, which apparently is a feature that allows applications to offload compositing-related work to the compositor.

Not sure if that is the sole reason wayland wine isn’t running w/ gamescope…
But if it is the underlying issue, the two solutions I can think of would be either:

• simply implement wl_subcompositor in gamescope

OR a partial solution (would only work in nested sessions, on wayland hosts):

• make a wrapper around wl_subcompositor that forwards the wl_subcompositor feature from the wayland host compositor that gamescope would be running under in a nested session? (Now that I think about it, this second idea would probably be a waste of time I guess???)

[KyunLFA]

Since I won't be creating a new issue, I don't feel too bad tagging some potential parties of interest. Not requesting the feature here, it's just the data for posterity. If you are one of the tagged, please disregard if occupied or simply uninterested. Apologies in advance for pinging. Barebones UGLY HACKY diff for getting a window running in the post below. TL;DR in the end.

@Joshua-Ashton @emersion @romangg @sharkautarch

Here are the findings:

0 (skip if caught up). Originally this was about announcing that Wine waylanddrv wasn't rendering in Gamescope due to missing wl_subcompositor. See the reg edit above to enable on newer Wine.

1. It already works on git HEAD. But only for nested, with an envvar override. Use gamescope --expose-wayland -- env WAYLAND_DISPLAY=wayland-foo wine PROGRAMHERE (foo = 0 for Plasma 6, 1 for Sway, depends on the compositor);

2. wl_subcompositor is needed for embedded mode. It's very straightforward to "implement" in Gamescope;

3. zwp_pointer_constraints_v1, turns out is another hard requirement that reared after wl_subcompositor. With a quick&dirty diff (subcompositor+contraints hack, see the post below), it's enough to render a window in embedded mode...

4. ...That will quickly segfault on (an invisible) cursor movement. You may then think it would be due to hacky unimplemented constraints, yet after I attempted to port back Pointer and cursor improvements #28, although it proved too difficult to do properly with my extremely limited skills, turns out the cause of the segfaults was not the wrong contraints, but a C++ stdlib runtime throw, std::get bad variant access with a wrong index (full backtrace below), from xwayland() calls in steamcompmgr.cpp in MouseCursor::paint, in the following lines:

uint32_t sourceWidth = window->xwayland().a.width;
uint32_t sourceHeight = window->xwayland().a.height;

Additionally, after applying a hack to proceed, same throw in the lines:

scaledX = (winX - window->xwayland().a.x) * currentScaleRatio_x + cursorOffsetX;
scaledY = (winY - window->xwayland().a.y) * currentScaleRatio_y + cursorOffsetY;

5. After hacking some resolution values to sourceWidth/Height and scaledX/Y, finally, at last we're rendering on Gamescope embedded without segfaulting, but since I could not implement valid pointer constraints, the cursor was stuck to the leftmost top side (only appears after moving);

6. Visual bugs plague the window in my system. Some of the text flashes in and out, window elements may be drawn as black rectangles or flicker, window is never fullscreen (pillarboxed) unless it randomly is, and popups like context menus fill the window. Here I'm at a loss what is causing it;

7. There is already a micro-compositor (Wayland kiosk) with Wine Wayland support (kind of)! That could be useful for figuring out exactly what is happening by checking their work. Cage, with the Implement pointer constraint. cage-kiosk/cage#300 PR applied on top, renders a wine notepad.exe window correctly in fullscreen.

TL;DR. 1.Nested already works; 2.wl_subcompositor is missing; 3/5.zwp_pointer_constraints_v1 implementation is needed; 4.There's a C++ runtime throw in MouseCursor::paint; 6.Text and window elements flicker and black textures where there aren't any; 7.Cage Kiosk already works embedded, looking there may prove useful.

Note: I will be away from the PC soon, so likely I won't be able to reply for a few hours, so sorry.

Update!! Wine wayland on embedded mode progress thanks to @sharkautarch !! The solution (for now) of the bad variant access was adding && input->type == steamcompmgr_win_type_t::XWAYLAND to the line if (input && !bForceHideCursor in steamcompmgr.cpp!! Will now move on to attempt to get a working cursor... Updates to be posted shortly over at my fork.

edit: Nope, couldn't get a working cursor :/ Not skilled enough atm

[KyunLFA]

I just realized, setting WAYLAND_DISPLAY to something other than gamescope's wayland display just runs the app without gamescope :/
