Direct access to GPU memory from within sandbox

[Winnie Poon]

thanks for your reply Michael.  I've also read discussion about installing Nvidia driver inside flatpak.  Is this another way to access the GPU memory without punching hole?

Why do I need to install Nvidia driver for Flatpak applications?<https://askubuntu.com/questions/1114324/why-do-i-need-to-install-nvidia-driver-for-flatpak-applications>
When I want to install an application from flatpak repository, it shows that flatpak also needs to install Nvidia driver. I've read about Flatpak in the flatpak documentation web site and it seems to have sandbox system and applications can only run in an isolated environment:

AFAIK currently you need to punch a hole in the sandbox using
`--device=dri`. Apps using WebKitGTK do this to support hardware
accelerated rendering, for example.
