STEPS TO REPRODUCE
1. Install the Arch Linux xwaylandvideobridge package: https://archlinux.org/packages/extra/x86_64/xwaylandvideobridge/
2. Attempt to run it from the terminal

OBSERVED RESULT
It crashes with the following output:

libEGL warning: egl: failed to create dri2 screen
ERROR:             ICD associated with VkPhysicalDevice does not support GetPhysicalDeviceCalibrateableTimeDomainsKHR
Aborted (core dumped)

EXPECTED RESULT
It starts normally.

SOFTWARE/OS VERSIONS
Linux: 6.7.5-arch1-1
KDE Plasma Version: 5.27.10
KDE Frameworks Version: 5.115.0
Qt Version: 5.15.12

ADDITIONAL INFORMATION
I ran XWayland Video Bridge from the terminal, as the desktop entry doesn't appear.

Comment 1 malikth32 2024-02-24 23:54:33 UTC

This is actually an issue with Mesa 24.0.1 as observed here: https://forums.developer.nvidia.com/t/mutter-x11-frames-is-unable-to-start-with-mesa-24-nvidia-550-rtx-4070tis/283055

After downgrading Mesa to 23.3.5, everything works as expected.
