--- Comment #1 from Axel Davy <vebveb at hotmail.fr> ---
This is due to Mesa DRI3 code not taking care of the DRI_PRIME env var.

As a temporary fix, the user can set LIBGL_DRI3_DISABLE in addition to
DRI_PRIME when wanting to use the secondary card.

A temporary patch could be mergedto not try the DRI3 path when DRI_PRIME is

The complete fix should be DRI3 DRI_PRIME support.
I hadn't time yet to rewrite the gallium dri3 code and to rebase the patches,
but they should be ready soon.
