Is this with wayland or X11?
Do you have QSG_RHI_BACKEND set to anything in your environment?
Can you try with qutebrowser --temp-basedir -s qt.force_software_rendering software-opengl?

Not sure what's going on here. This message seems quite confused:

QOpenGLContext::makeCurrent() called with non-opengl surface 0x5fc762297640

but I'm not seeing anything recent show on for that error on a web search.

@T0MuX any update? FWIW this doesn't seem like anything qutebrowser could fix.

Hi guys, sorry for the little delay. I have no QSG_RHI_BACKEND set.
I tried with qutebrowser --temp-basedir -s qt.force_software_rendering software-opengl, the only difference is I don't see anymore the 3 WARNING and the exporting buffer loop. Now it's :

[t0mux@atelier-pc ~]$ qutebrowser --temp-basedir -s qt.force_software_rendering software-opengl

But same result in Xorg :

EDIT : just to remind, it's OK with PyQT5 wrapper :

qutebrowser --qt-wrapper PyQt5 --temp-basedir
