PrusaSlicer not running with flatpak when running on dedicated gpu

[PredellaN]

Description of the bug

When starting prusaslicer with "flatpak run com.prusa3d.PrusaSlicer", the application starts and works normally.
When starting with:

• "flatpak --env=__NV_PRIME_RENDER_OFFLOAD=1 --env=__GLX_VENDOR_LIBRARY_NAME=nvidia run com.prusa3d.PrusaSlicer"
• "switcherooctl -g 1 com.prusa3d.PrusaSlicer"
  The application stops here:

nicolas@pop-os:~$ flatpak run --env=__NV_PRIME_RENDER_OFFLOAD=1 --env=__GLX_VENDOR_LIBRARY_NAME=nvidia com.prusa3d.PrusaSlicer 
--------------------------------------------------------------------------
Message: 21:35:42: Starting PrusaSlicer flatpak with entrypoint script
--------------------------------------------------------------------------
nicolas@pop-os:~$

Starting the 2.8.0 AppImage version with switcherooctl -g 1 or with the environment variables specified before, the application starts on the dedicated GPU as intended. Other flatpak applications i am using run on the dedicated GPU without issue.
Enabling device=dri won't fix the issue.

Project file & How to reproduce

• install the flatpak version of prusaslicer on a device with hybrid graphics
• run prusaslicer with either of the above mentioned commands

Hello, @PredellaN , Could you check if PrusaSlicer has permission to use the GPU? You can add the necessary permissions using this command: flatpak override --gpu=all com.prusa3d.PrusaSlicer. Personally I would recommend flatseal to set/manage flatpak permissions in general.

Hello @Jan-Soustruznik ,

nicolas@pop-os:~$ flatpak override --gpu=all com.prusa3d.PrusaSlicer
error: Unknown option --gpu=all

I assume you meant --device=all , however it doesn't solve the issue (it is already on by default). --device=dri also doesn't solve the issue
