Steps to reproduce:

1) Have dual monitors
2) Enable PP_OVERDRIVE_MASK by flipping the appropriate bit in
amdgpu.ppfeaturemask. (For my configuration I used: 0xfffd7fff)
3) See artifacting.

When using default featuremask, or when using a single monitor with the
overdrive bit enabled behaves correctly. I heard multiple people who have t=
he
same issue, so it does not seem related to my setup.
