DRI PRIME 0

I have a Razer Blade Stealth late 2016 with a Razer Core V1 and an RX 560.

Arch Linux

Linux stealth 5.2.1-arch1-1-fsync #1 SMP PREEMPT Mon Jul 22 17:40:06 PDT 20=

x86_64 GNU/Linux

mesa-aco-git 19.2.0_devel.114720.5c6077221dd-1 (Also happens on normal mesa=
-git
and mesa stable)

With only the AMDGPU enabled for Xorg, DRI_PRIME=3D1 attempts to use Intel,=
 falls
back to AMD as expected, but has the weird behavior of completely bypassing
vsync. DRI_PRIME=3D0 works as expected

Expected behavior is to ignore the Intel card since it's not currently load=
ed
in Xorg. I can obviously set DRI_PRIME=3D0 and be fine, but the DRI_PRIME=
=3D1
behavior seems to be a bug.
