The client area subsurface (the target of Vulkan rendering) is not going to be presented properly (or at all) by the compositor if its parent surface is not mapped or doesn't have the right size, even though the window may be visible from Wine's perspective. To avoid this issue, ensure that the parent surface has up-to-date contents in terms of size, in case these haven't been provided yet, or will never be provided (e.g., when the Vulkan rendering is fullscreen). --- dlls/winewayland.drv/vulkan.c | 2 + dlls/winewayland.drv/wayland_surface.c | 68 ++++++++++++++++++++++++++ dlls/winewayland.drv/waylanddrv.h | 3 ++ dlls/winewayland.drv/window.c | 1 + 4 files changed, 74 insertions(+)
