Yes
System Info
Void x86_64 river (wlroots) Intel i3-2330M
Package(s) Affected
libva
Does a report exist for this bug with the project's home (upstream) and/or another distro?
https://github.com/intel/intel-vaapi-driver/issues/419
Expected behaviour
vainfo should give all the hardware codecs
Actual behaviour
vainfo looks for a symbol wl_drm_interface in /usr/lib/libEGL_mesa.so.0, can't find it and fails.
Steps to reproduce
Trying display: wayland
libva info: VA-API version 1.22.0
libva info: User environment variable requested driver 'i965'
libva info: Trying to open /usr/lib/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_1_9
error: failed to resolve wl_drm_interface(): /usr/lib/libEGL_mesa.so.0: undefined symbol: wl_drm_interface
libva error: /usr/lib/dri/i965_drv_video.so init failed
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

Research direction
Start by reproducing the reported vainfo command and compare its Wayland output with the linked upstream intel-vaapi-driver issue. Trace the affected libva package and driver initialization around the missing wl_drm_interface symbol; done means vainfo initializes successfully and reports the available hardware codecs on this system.
