Wayland doesn't work

[danilw]

Wayland build with this ON

Result error/crash:

Continue of #11 :

Even if I edit related file - NRISamples/BUILD/_deps/glfw-src/src/wl_window.c - line 2811-2860 removing related to cursor.
It will run with 100% single core usage - window will be "empty"(no borders - just app icon)

Main problem to debug further - there no "example" that use GLFW_EXPOSE_NATIVE_WAYLAND with Vulkan.

GLFW example use glfwCreateWindowSurface - that different and require huge code-logic changes.

I also remember - common Wayland-Vulkan initialization error is (there is done correctly) - https://github.com/glfw/glfw/blob/master/tests/triangle-vulkan.c#L598

    VkExtent2D swapchainExtent;
    // width and height are either both 0xFFFFFFFF, or both not 0xFFFFFFFF.
    if (surfCapabilities.currentExtent.width == 0xFFFFFFFF) {
        // If the surface size is undefined, the size is set to the size
        // of the images requested, which must fit within the minimum and
        // maximum values.
        swapchainExtent.width = demo->width;
        swapchainExtent.height = demo->height;

        if (swapchainExtent.width < surfCapabilities.minImageExtent.width) {
            swapchainExtent.width = surfCapabilities.minImageExtent.width;
        } else if (swapchainExtent.width > surfCapabilities.maxImageExtent.width) {
            swapchainExtent.width = surfCapabilities.maxImageExtent.width;
        }

        if (swapchainExtent.height < surfCapabilities.minImageExtent.height) {
            swapchainExtent.height = surfCapabilities.minImageExtent.height;
        } else if (swapchainExtent.height > surfCapabilities.maxImageExtent.height) {
            swapchainExtent.height = surfCapabilities.maxImageExtent.height;
        }
    } else {
        // If the surface size is defined, the swap chain size must match
        swapchainExtent = surfCapabilities.currentExtent;
        demo->width = surfCapabilities.currentExtent.width;
        demo->height = surfCapabilities.currentExtent.height;
    }

Many "old" x11-code expect "set size to window-surfce from code" when in Wayland - Wayland set size of surface. (something like that)

idk if this is the case here

P.S. maybe this is not case here - sorry for miss information.
I remembered - Vulkan Validation layers will print "error in creating swapchain size" - like that - but I launched these Wayland examples with validation layers - no errors just single not related warning.
This is second reason made me confuse - usually there clean wayland crash or validation layers print something - here is nothing.

Thanks Danil. With your help we managed to get X11 working and reached some success in Wayland support! Very appreciated! This issue is bigger and requires more analysis and debugging. I don't have a Linux machine, but I will ask a colleague to help.
