    radeonsi: enable OpenGL 4.3

The first scenes in the Unreal elemental demo that contain lava renders it black, later scenes lava looks normal.

FWIW I've seen this on nouveau and i965 as well. I wouldn't be surprised if this were a bug in the demo. The demo uses the GL 3.2 renderer when run on nvidia blob, among other things.

Per comment #1, reassigning to core for now.

Comment 3 Timothy Arceri 2018-09-15 01:33:17 UTC

As per comment #1 when running on the Nvidia blob is always takes a GL 3.2 path. When I replay an apitrace taken on radeonsi the Nvidia blob also renders the lava black so I this does indeed seem to be a bug in the demo. Closing.
