https://github.com/qutebrowser/qutebrowser/issues/3276 seems like a related issue, could you try using software rendering as suggested there? Also what graphics driver/card are you using?

[furrycatherder]

I'm using an NVIDIA GeForce GTX 970 with the nvidia-ck-bulldozer package from repo-ck. I see the same error with software rendering enabled, and adding myself to the video group didn't solve it either.

[The-Compiler]

Did you upgrade your graphics driver and not reboot yet?

[furrycatherder]

Well, I thought I had, but recompiling and rebooting fixed it for me. Closing.
