Cloud gaming performance degredation with iHD

So, just wanted to post this as it caught me off guard when my Manjaro Linux install upgraded from 19 to 20. It is Arch linux based. I think the default changed from i965 to iHD during this upgrade.

I use cloud and game streaming software to play games on my Linux laptop from my gaming desktop. I use Parsec primarily, and Rainway as a backup.

When the iHD driver is active, Parsec and Rainway both degrade within a few seconds to severe decoding latency, making these unusable.

I only found out about it because I went to the Parsec discord, and a community manager happened to have the same issue and pointed it out.

As soon as I set `LIBVA_DRIVER_NAME=i965` all my performance came back fully.

Parsec uses a desktop app (thought I believe its an Electron app of some sort with Native bindings for streaming), and Rainway runs entirely in chromium. Both use h264 and/or h265 if you support it.

Even with h264, it was a huge difference in performance between the 2 drivers.

I don't know where and what logs/debug information would be beneficial, so if there is anything I can provide to help, I can definitely provide it.
