**Notes**: 

- I'm using an hybrid graphics setup (Intel + NVidia) on Wayland at Fedora 35. I don't know if this affects this bug. I just saw this bug: <https://github.com/NVIDIA/egl-wayland/issues/41>
Comment 1 Vitaly 2021-11-02 16:44:44 UTC 
It looks like another GNOME 41 issue, related to Wayland+Qt. Please try "Gnome on X11" session.
Comment 2 felipehw 2021-11-12 12:42:45 UTC 
I tried with "Gnome on X11" session and it works.
By now, I'm using Wayland session and running Ghostwriter RPM from a Fedora 34 container (Toolbox).
Comment 3 Vitaly 2021-11-12 13:04:51 UTC 
This issue is related to Qt5 QtWebEngine crashes on Wayland+GNOME.
Comment 4 Kevin Kofler 2021-11-12 13:09:35 UTC 
According to your link, this is a bug in the proprietary NVidia driver.
