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).


Make sure that the apps have access to your discrete graphics card. Flatseal allows you to manage flatpak permissions
The permission OP should look for is DRI.
