Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.2-rc2 Flatpak version

Operating System (OS)

Linux

OS Version

Fedora 43

Additional system information

Ryzen 9 5950X with Radeon 7900 XTX. It has a secondary Nvidia card that is not used (nouveau driver).

Printer

Multiple tested but not related to printer

How to reproduce

Install OrcaSlicer 2.3.2-rc2
flatpak run io.github.orcaslicer.OrcaSlicer
Main window shows up but no build plate in the 3D view under "Prepare" or "Preview" tabs

Actual results

Running the 2.3.2-rc2 from the command line seems to get a Mesa error:

MESA: error: dri3_alloc_render_buffer:1626 xcb_dri3_pixmap_from_buffer[s] failed
MESA: error: X error: 11

Running the program with LIBGL_ALWAYS_SOFTWARE=1 makes it work (but it is very slow):
LIBGL_ALWAYS_SOFTWARE=1 flatpak run io.github.orcaslicer.OrcaSlicer

Also, Zink seems to work:
MESA_LOADER_DRIVER_OVERRIDE=zink flatpak run io.github.orcaslicer.OrcaSlicer

Expected results

It should work as it does in the 2.3.2-rc1.

Anything else?

Documenting here in case people run into it. The workaround for this issue is to use Zink GL driver:
MESA_LOADER_DRIVER_OVERRIDE=zink flatpak run io.github.orcaslicer.OrcaSlicer
