yochananmarqos [1] filed a request to merge vulkan-caps-viewer [2] into vulkan-caps-viewer-wayland [3]: The existing vulkan-caps-viewer package does not run on X11, only Wayland. I've created separate versions built for each. Upstream releases X11 and Wayland versions of the AppImage and there are corresponding binary AUR packages as well.
