orca-slicer: App does not display correctly on KDE Plasma and Wayland and is unusable.

[colin-small]

Nixpkgs version

• Unstable (26.11)

Describe the bug

When launching the application it doesn't display the UI correctly and is unusable. I am using KDE Plasma and Wayland on unstable.

Steps to reproduce

Launch orca-slicer in any way: Plasma app menu, terminal etc..

Expected behaviour

I expect the application to launch and look normal and be usable.

attached crash logs, additional context below from terminal

Additional context

Additional info from the terminal.

(orca-slicer:10119): Pango-CRITICAL **: 19:16:57.747: pango_font_description_set_size: assertion 'size >= 0' failed

(orca-slicer:10119): GLib-GIO-ERROR **: 19:16:58.053: No GSettings schemas are installed on the system
Aborted                    (core dumped) orca-slicer

I noticed that if I launch it with GTK_USE_PORTAL=1 it seems to launch normally and be usable.

But when closing the app windows it still crashes.

On the terminal after closing the app windows it also displays:

I had the same issue, was not able to export any files. Using older version of the package for now
