On my Ubuntu-based system I just got an update for the proprietary Nvidia driver. After restarting the OS, 3D acceleration in flatpak apps is broken, because apparently, flatpak-update only updates the Nvidia driver that is currently in use.
This would be something that the Ubuntu packaging for the proprietary NVIDIA driver should do. Discover doesn't know how to do this. Please report this to the Ubuntu or Debian packagers. Thanks!

Maybe a proper fix belongs to libflatpak, but as a workaround, discover could compare the output of $ flatpak --gl-drivers with (e.g.) $ ls /usr/lib/x86_64-linux-gnu/libnvidia-*.so.*.*.*
As clarification: flatpak needs the NVIDIA userspace driver part (libnvidia-*.so etc.) copied into the sandbox and it needs to have the exact same version as the currently loaded kernel module (nvidia.ko). Flatpak checks the kernel module version in /sys/module/nvidia/version and downloads the NVIDIA driver from the webserver and copies the libs to /var/lib/flatpak/runtime/org.freedesktop.Platform.GL.nvidia-XXX-XX-XX/x86_64/1.4/active/files/extra.
This is something libflatpak should detect. If there's new API that we'd need to implement, we could do that. But as is there's not much we can do. @eszlari, can you report it upstream to see how we should better deal with this issue?

Marking as upstream again for now. We can re-open it if the flatpak people say we need to do it I guess.
