**Additional context**
Add any other context about the problem here.

The bug is about missing texture previews for default capes in the 5zig options GUI when connected to a server. Look for cape rendering code in the GUI classes, likely under a 'capes' package or menu. Check how textures are loaded and displayed, and see if server connection affects resource loading. Test by reproducing the issue in a development environment and inspecting the texture paths.
