I signed up for the Hotfix before I knew anything and got it last night.  I
also got an email from someone at Nvidia wanting more data about my problem.

Turns out if I turn off HDMI 2.0/HDR on my TV, I no longer get the random
blank screens for a second or 2. Even though every piece of equipment in
the chain is HDMI 2.0 compatible, with version 9, I have issues if it's
activated on the TV.

I tested Leanfront and it's still smooth as expected. I have not had time
to test mythfrontend on v31 with my worst case test videos, but will today.

Turning off HDR is not a big issue for me. The picture is still 4K and it
looks good.  Mythtv content is always 1080i or 720p over here.
