i know this is not an unfixable bug, in fact, i know the fix, but i am still making this issue because you have to set an obscure environment variable in order to get the orcaslicer preview to work.

my fix:
running this in the terminal and then running orcaslicer with flatpak fixes the issue for me:

flatpak override --user --env=GBM_BACKEND=dri io.github.softfever.OrcaSlicer

(i got this fix issue from a more or less unrelated issue)

this issue has existed for at least 2 years.
link to reddit post about this from 2 years ago

there have been multiple issues on this, all of which seem to have been more or less ignored, apparent by the fact that it has yet to be fixed.
issue 1
issue 2

as far as i know, this is related to nvidia drivers and linux.
also on the exact same system, it works fine on windows with the normal installation process.

also, the obscure flag forces orcaslicer to use cpu rendering, evident by the fact that all my 16 cores go crazy when i simply rotate the camera and i also get about 2fps.

(all 16 cores are almost fully green in the top right corner)

please someone fix this. this fix is long overdue in my opinion.
