Well, I would guess so. After adding X11:XOrg project to obs in 2001 and
maintaining it with more than 300 packages since more than 20 years now.

Seems after changing the build project for 15.4 to 
openSUSE:Leap:15.4:Update gcc12 packages are found now ... Mesa 22.3.3 now also
building against Leap 15.4.

You stumbled across the buildrequires to gcc12. Easy for you. My collegue
figured it out the hard way. But long after Mesa 22.3 had been released. It's
still nowhere documented that now gcc12 is needed for building. :-(

No idea why this is needed on a Intel-only GPU system. Maybe you have a
Intel/nVidia combination and didn't notice it yet? Running 'inix -aG' would
help to figure it out.

There is no VDPAU driver available for Intel. So apparently you're using the
VDPAU wrapper library, which then uses VA-API as backend.

package: libvdpau-va-gl
check /etc/profile.d/libvdpau-va-gl.sh

Maybe VDPAU_DRIVER is set to 'nvidia' for some reason. It should be set to
'va_gl'.
