I recently did an update for Soundux (flatpak) that showed up and it caused Soundux to white screen and I haven't been able to resolve this issue.

When I launch Soundux through flatpak in terminal with flatpak run io.github.Soundux, I receive the following:

$ flatpak run io.github.Soundux

and an accompanying window opens with a white screen and everything just hangs.

I have

• reinstalled gtk3-nocsd
• reinstalled libgtk3-nocsd0
• added export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libgtk3-nocsd.so.0 to ~/.bashrc
• installed libcanberra-gtk-module
• installed unity-gtk3-module

Rebooted a few times post installations

@ProjectSynchro Tagging you here because you might have some insights as you've worked on this

[ProjectSynchro]

Interesting, looks like there is a missing permission that is required for that specific library.

I'll spin up an Ubuntu 22.04 VM and see if I can reproduce.

All libraries should be pulled in from the runtime.. weird..

[ProjectSynchro]

On a fresh Ubuntu 22.04 install, I was able to run the Soundux flatpak without any issues:

The warnings about "canberra-gtk-module" and "unity-gtk-module" are benign.

It looks like there are issues with the version of libwebkitgtk in the Gnome 44 runtime and the NVIDIA proprietary driver: https://bugs.webkit.org/show_bug.cgi?id=254807

This may be related to their NVIDIA hardware, does Soundux work if they run: flatpak run --env=WEBKIT_DISABLE_DMABUF_RENDERER=1 io.github.Soundux?

Additionally it may help if they update their drivers, check for any flatpak updates, and run flatpak repair.

Thanks for the investigation. Waiting for confirmation to close this

Upstream issue with NVIDIA drivers. If anyone stumbles upon this issue add the environment variable WEBKIT_DISABLE_DMABUF_RENDERER=1 to fix.
