Occasional black screen for a few seconds on High Sierra QEMU/KVM machine.

Asus X570 mobo latest BIOS

Ryzen 7 3700x

nVidia GTX 1070

I followed the guide on Linus Tech Tips along with some PCI pass through guides, and I got it set up pretty painlessly.

Everything worked great out of the box except graphics acceleration. Fixed that by installing the nVidia web drivers.

Now the High Sierra machine runs like lightning. It actually gets a better GeekBench score than on bare metal Windows.

My only problem now is black screens. It will randomly black screen for a few seconds and then come back up. It happens a few times a day seemingly randomly.

Beyond installing the nVidia web drivers I have done ZERO tweaks or customization so far. Is there anything I can try to alleviate this problem?
