The data loading module fails after the first time and results in a blank window. Only way to fix it is to restart Slicer.

My platform is Fedora 36 (linux) with wayland.  
Slicer version - Slicer-5.3.0-2023-01-28  
I’m attaching the terminal output along with the slicer log to help solve this issue.

I can build slicer on Debian 12 using wayland.

I use the following startup script

```auto
#!/bin/bash

__NV_PRIME_RENDER_OFFLOAD=1__ GLX_VENDOR_LIBRARY_NAME=nvidia QT_XCB_GL_INTEGRATION=xcb_egl QT_WAYLAND_SHELL_INTEGRATION=ivi-shell QT_WAYLAND_CLIENT_BUFFER_INTEGRATION=wayland-egl $@ -platform wayland

```

The first entries I use because I work on a laptop using hybrid graphics. Sometimes my entire computer freezes. I needed to install a different version for SSL to make it work.

Interesting - maybe that should go in slicer’s readthedocs somewhere.
