Thanks for the bug report. This appears to be either a hardware problem or a bug in the Nvidia driver. I think most likely it's due to insufficient HDMI cable bandwidth. Please ensure you are using an HDMI 2.1 certified cable capable of at least 40 Gbit/s. An HDMI 2.0 cable will not be good enough.
