            Bug ID: 2196198
           Summary: Program crashes when trying to open preferences due to
                    wayland protocol error
           Product: Fedora
           Version: 38
          Hardware: x86_64
                OS: Linux
            Status: NEW
         Component: tikzit
          Keywords: Desktop
          Severity: high
          Assignee: redhat(a)flyn.org
          Reporter: fedora(a)joshuanoeske.de
        QA Contact: extras-qa(a)fedoraproject.org
                CC: epel-packagers-sig(a)lists.fedoraproject.org,
                    redhat(a)flyn.org
  Target Milestone: ---
    Classification: Fedora



When I try to open the preferences, the whole application crashes. I can
reproduce that reliably. The output of tikzit to stdout/stderr is the
following:

QSocketNotifier: Can only be used with threads started with QThread
Attribute Qt::AA_EnableHighDpiScaling must be set before QCoreApplication is
created.
QSocketNotifier: Can only be used with threads started with QThread
The Wayland connection experienced a fatal error: Protocol error

Reproducible: Always

Steps to Reproduce:
1. Open TikzIt using Wayland as display server.
2. Open preferences via toolbar.
Actual Results:  
Whole program crashes

Expected Results:  
Preferences open

My system is fully upgraded, so I am using the qt packages version 6.5.0 and
Gnome/mutter 44.1. I have also tried downgrading Gnome and mutter to version
44.0, as well as the qt packages to 6.4.3, but both did not help to solve the
problem.
