Absolutely the same for me. Whenever I encounter a problem I'm pretty sure nobody else has encountered before (or has not written about it at least), ChatGPT writes complete nonsense. On stuff that's a bit obscure, but not really (like your Vulkan example), ChatGPT tends to write 60-95% correct code, that's flawed in the exact ways a noob wouldn't be able to fix. In this case, nicking code from Github seems to fix the issue, even if I need to adapt it a bit. Then comes the licensing issue. Often, when searching for an obscure topic, the code ChatGPT generates is very close to what's found on Github, but said code often comes with a non-permissive license, unlike what the AI generates.
