I did notice that sometimes the flatpack version of a program didn’t seem to recognise my graphic card. I’ve seen this first with Handbrake, but also with other apps it seems that i get better performance with the mint package or the official ppa. Did anyone notice anything similar?
I’m using Mint on an old HP laptop with a nvidia card so if anything I’m glad that everything is recognised properly (safeboot disabled).


My best guess is that it’s not a Flatpak permissions issue as others are claiming; the software is just trying to use your iGPU (which is usually crappy) instead of your dGPU.
Try taking whatever command you use to start the program and tacking
DRI_PRIME=1on the front. This has often worked for me on applications regardless of whether they’re native or Flatpak.
