Comment # 5 on bug 1208711 from Stefan Dirsch

I'm afraid this won't get fixed still for Leap 15.4. Mesa is just too old
there.
Could you give it a try with a Tumbleweed Live image? If it works it will most
likely also work with Leap 15.5. Of course you can also try with a Leap 15.5
Live image - once available. Currently it's not I believe (still Beta).
