Missing permission to access /dev/dri/renderD128

[dscp46]

Describe the bug
When installed with flatpak and launched on a wayland session, YUView warns of being unable to access /dev/dri/renderD128.
Significant performance impact is noticeable.

QSocketNotifier: Can only be used with threads started with QThread
libEGL warning: wayland-egl: could not open /dev/dri/renderD128 (Aucun fichier ou dossier de ce type)
