SOLVED (code-error and not an actual issue (although perhaps the window- selector glitching-out with improper code should be addressed)):
From (https://www.reddit.com/r/vulkan/comments/g1ikb0/gnome_wayland_not_working_with_vulkan_on_debian/): Thanks, I tried putting wl_proxy_marshal((struct wl_proxy *) xdg_surface, XDG_SURFACE_ACK_CONFIGURE, serial); (xdg_surface_ack_configure() equivalent) before every vkQueueSubmit (I know that you meant to put the ack in response to events, but while trying to make things work, I thought that it needed to be before every vkQueueSubmit), and the window-menu started working, but events weren't triggering. I then discovered that I needed to call wl_display_roundtrip() every frame and only call xdg_surface_ack_configure after certain events (xdg_surface_listener's and xdg_toplevel_listener's configure events). This is what I ended-up with in my draw loop: retStatus = wl_display_flush(display); if(retStatus == -1) { //TODO: use poll() to wait until display fd is writable again, and call wl_display_flush again exit(1); } wl_display_roundtrip(display); //blocks submitInfos[0].pCommandBuffers = &commandBuffers[imageIndex]; vkQueueSubmit(graphicsQueue, 1, submitInfos, fence); wl_display_dispatch_pending(display); ** Changed in: gnome-desktop3 (Ubuntu) Status: New => Invalid ** Changed in: gnome-desktop3 (Ubuntu) Assignee: (unassigned) => a b (the-coder) ** Changed in: gnome-desktop3 (Debian) Assignee: (unassigned) => a b (the-coder) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-desktop3 in Ubuntu. https://bugs.launchpad.net/bugs/1872871 Title: Xdg-Shell Stable not working properly Status in gnome-desktop3 package in Ubuntu: Invalid Status in gnome-desktop3 package in Debian: New Bug description: I'm trying to run a simple Vulkan program on Debian Testing (GNOME desktop using Mesa Vulkan implementation), but it seems like there might be an issue with GNOME, since none of the xdg_shell (stable) callbacks seem to be working and resizing the window doesn't work (although the window is rendering correctly at least). Swapping to another window, and then going to the list of windows to choose from causes the window's preview (on the list of windows) to be partially- hidden behind other windows and be unclickable (note that this is GNOME's window-selection screen(under activities), not switching tabs like on Windows). None of the Wayland (including xdg-shell) functions are returning errors and Vulkan validation layers are not reporting any warnings. is anyone else experiencing this and/or knows a solution to this? Could this be because I'm using xdg-shell stable (xdg_wm_base), which was released relatively recently? I'm using a .h file (generated from the xdg-shell xml on my system) to define the interfaces (not a static or dynamic library), but I believe that this is correct, and that there is no xdg-shell dynamic library to load. I was using wl_shell before this, and the window-selection screen worked properly while using wl_shell.
