How to reproduce

1. run qutebrowser
2. wait for screen to automatically turn off after 15 minutes
3. move mouse to turn screen back on (in my case this is done with swaymsg "output * dpms on")
4. qutebrowser crashes in the moment when the screen turns back on

[The-Compiler]

This is most likely an issue with the underlying Qt library and not qutebrowser. Could you please try qutebrowser-git from the AUR, run it with QUTE_QT_WRAPPER=PyQt6 qutebrowser --temp-basedir and see if it happens there too?

[tobip]

I would love to try this, but will it keep my config when I reinstall qutebrowser from AUR?

[The-Compiler]

Yep! (Un)installing packages should never touch anything in your home directory - and with --temp-basedir, qutebrowser won't either, so your cookies and such won't be upgraded to the new version.

[tobip]

I guess I'm missing something. Need more help.

[The-Compiler]

Ah, yep - you'll need python-pyqt6-webengine too, that's not a dependency yet because it's not the default yet.

[tobip]

Got it.
Can't reproduce error in qutebrowser-git.

[The-Compiler]

Assuming this is an upstream Qt issue that's been fixed then - nothing qutebrowser can do here I'm afraid, other than finishing the move to Qt 6 (see #7202, hopefully the default will switch this week).
