Vulkan errors from headless chromium

Headless chromium gives me many errors:

```

I do not get them without `--headless`, but I want to run it in headless mode so I can print webpages. The printing seems to work regardless of the errors, so whatever they are, they're not too important. But they clutter up output and make it hard to see whether the actual task (printing) failed.

GPU acceleration is not important to me. The page I am working with is very simple and would be fast enough regardless.

How can I make the output less noisy? I can't just send everything to `/dev/null` because occasionally there might be important messages.
