At the moment GL/VK content can only be presented in top-level windows, since child windows are not backed by Wayland surfaces. This MR adds support for such scenarios, in a few gradual steps:
1. Create Wayland (sub)surfaces for all child windows, anchoring them to their parent surface, which may also be a child window surface (i.e., we support GL/VK in nested child windows). This approach works, but it pollutes the compositor with mostly unused, and possibly nested (sub)surfaces. We will deal with this later in the MR. 2. Ensure that the child window (sub)surfaces are properly updated and reconfigured, and support WS_POPUP <-> WS_CHILD style changes (reparenting etc). 3. In the last commit, improve efficiency by creating (sub)surfaces only for the child windows needed by GL/VK, and anchor them directly to the parent toplevel. This removes (sub)surface bloat and unnecessary nesting, the trade-off being some extra complexity when dealing with updates.
Note that this MR doesn't clip GL/VK child window contents at the moment.
The subsurface mechanism introduced in this MR could also handle other kinds of windows in the future, for example display and properly position transient windows, menus etc.

Windows supports changing between the WS_CHILD and WS_POPUP window styles which requires a Wayland surface role change between wl_subsurface and xdg_toplevel.
Since Wayland doesn't support changing a surface's role, to support this scenario we recreate the Wayland surface and adjust any related subsurfaces to use the new parent surface. --- dlls/winewayland.drv/wayland_surface.c | 31 +++++++++++++++ dlls/winewayland.drv/waylanddrv.h | 2 + dlls/winewayland.drv/window.c | 54 +++++++++++++++++++++----- 3 files changed, 78 insertions(+), 9 deletions(-)

Wayland surfaces for child windows are currently only needed to render GL/VK contents, so instead of creating them for all child windows, create them only when GL/VK needs them.
Furthermore, these child window Wayland surfaces will now be anchored directly to their top-level parent to avoid unnecessary nested subsurface chains. --- dlls/winewayland.drv/opengl.c | 2 +- dlls/winewayland.drv/vulkan.c | 2 +- dlls/winewayland.drv/waylanddrv.h | 1 + dlls/winewayland.drv/window.c | 97 +++++++++++++++++++++++++++---- 4 files changed, 90 insertions(+), 12 deletions(-)

Possibly what was discussed in https://gitlab.winehq.org/wine/wine/-/merge_requests/6025#note_75558, which first commit works around?

Thanks, I already have that fix applied (locally), so there is something else going here, likely due to the nested locking of parent-child wayland surfaces.

Somewhat... This MR supports child window rendering for both GL and VK, but not other process rendering.
