[Bug]: Disconnected from web VNC, using VNC directly "works"

Describe the Bug

https://github.com/user-attachments/assets/ab61904b-a454-4597-9133-9660ac283b31

If I connect directly using TightVNC it works correctly (but shows an extremely slow Flatpak download)

Steps to Reproduce

  1. Launch the Intel/AMD compose file with /dev/dri/card0 mapped
  2. Try to connect with web VNC

Expected Behavior

Steam login screen shown

I’m seeing the same issue in my deployment; was working fine before I updated to the latest NVidia drivers (v575.x), but looks like the issue presents even without using hardware acceleration.

Getting the same on a Skylake iGPU, if I disable sound in the web VNC viewer it's able to stay connected.
