Dunno... I manage to use nvenc for transcodes in windows without the UI freezing. I had similar issues with multiple monitors the last I tried... off server my htpc runs ubuntu, and I swear at least once a month I consider switching it back to windows (gigabyte brix hardware, all intel, like nuc), and the hdmi audio driver via intel/ubuntu is a consistent source of pain.

I love it for server-side workloads headless... but UI on linux still isn't nearly as consistent as it is on even windows, let alone mac.
