Crash when changing colour in style or editing text colour

Quick research brought up references to using Gtk.init() to solve this error, but not sure of the full context.

Will see if I can recreate in Ubuntu 22.04 in a few hours.

GNS3 2.2.33.1 OS: Manjaro GNOME version: 42.3 Windowing system: Wayland QT version: 5.15.5

Looks to me like an issue with QT trying to get initial GTK information. May be due to GTK4 in GNOME 42.x?

I can't reproduce this issue. I suspect a Qt bug, have you tried with version 5.15.7?

Will see if I can recreate in Ubuntu 22.04 in a few hours.

Have you managed to recreate it on Ubuntu 22.04?

@eantowne do you have any update about this? thanks :)

[eantowne]

@grossmj I have not been able to recreate this in my current install. I need to test against a few other distros still.

Sorry for the delay.
