Yeah, someone else reported the same as well:
https://github.com/The-Compiler/qutebrowser/issues/1819

You can probably make it work by installing mesa-libgl but that'll
conflict with nvidia-libgl :-/

This change in Qt *might* help:
https://codereview.qt-project.org/#/c/167643/
...but for some reason it's been abandoned.

You currently can't. I opened
https://github.com/The-Compiler/qutebrowser/issues/1976 for it, as it
sounds useful indeed.
