<pre>Due to DRI_PRIME=1, libGL tries to initialize the i965 driver with DRI3, which
fails:
libGL error: Different GPU, but blitImage not implemented for this driver
libGL error: failed to load driver: i965
So it falls back to DRI2, which uses the AMD GPU, because the Intel one wasn't
initialized in Xorg. DRI2 doesn't support sync-to-vblank via PRIME.
Reassigning to Mesa for now, but DRI_PRIME=1 really isn't intended to be used
with a single GPU.</pre>
