Doesn't play well on Fedora 41

The Wayland connection experienced a fatal error: Protocol error

System Journal shows:
Jan 10 15:25:40 Tardis.-name-.net gnome-shell[5948]: WL: error in client communication (pid 166306)

This worked just a few weeks ago - even with a slightly older version of QtTinyS.
Would appreciate guidance on how to dig further and even how to resolve.
Thanks!

Fedora 41
Python 3.13.1
python3-QtPy-2.4.1

The only system I have that uses Wayland is my Pi4b running the latest PiOS and it works ok there. My desktop and Pi have Python 3.11.2, I haven't tried 3.13.1. The 'WL: error in client communication' must be a clue. I assume you have set your user in the correct groups? I have only seen strange thread messages when I have tried to update a GUI from inside a thread, but QtTinySA doesn't do that. Does the .bin executable work?

[g4ixt]

Please let me know if the latest release v1.0.2, built using Github 'runners' works ok.

Greetings and thanks. I posted today's experience with 1.0.2 in the grups.io reflector. Took me too many steps to get it to launch. And it'll do just that, until I set the frequency range to 144.00Mhz to 148.00mhz and click on Run

TinySA Ultra v1.4-196-g1e9c187.

./QtTinySA
A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.2.2 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

I believe I have all the suggested version levels installed. Just need to know how to build the thing myself to try again.

[g4ixt]

I didn't specify the version of numpy, but I currently do use 1.x because that's what is current in Ubuntu 24.04 LTS and Anaconda (and I use the Spyder IDE for writing code). You could try creating a VENV to save changing your main versions.

This is one of the reasons why I stay on the LTS version for my main machine.

Does the Linux executable run ok?
