Hi Blobfish,

Thanks for these fixes and giving it a try, I want to ask if you have faced any performance issues while resizing window? Any other feedback is appreciated...

Hi @blobfish ,

When I tired to build I ma getting followig error:

[ 97%] Building CXX object src/vsg/CMakeFiles/vsg.dir/platform/wayland/Wayland_Window.cpp.o
In file included from /home/vasanth/practice/VulkanSceneGraph-personal/src/vsg/platform/wayland/Wayland_Window.cpp:4:

175 | .wm_capabilities = xdg_toplevel_handle_wm_capabilities};
|

I can see that following apis are not compatible with my system:
wm_capabilities, axis_value120 and axis_relative_direction

Is seems like some new apis are added in later versions, we need to find a mechanism which can identify the target version of the wayland and compile accordingly, this seems more work than what I initially anticipated :(

Or for time being we can drop these apis for now and ignore the warnings.

@blobfish you can give following a try:

void WaylandRegistryState::registry_add_object(void *data, struct wl_registry *registry, uint32_t id, const char *interface, uint32_t version) {
WaylandRegistryState state = static_cast<WaylandRegistryState>(data);
std::cout << "Interface: "<< interface << " Version: " << version <<std::endl;

this will output the capabilities of the wayland in your system and its version

@robertosfield other than that I see no issues with this changes, you can take a call here...
