I’m not really sure, sorry. I’ve read that it’s getting better but I expect it won’t work as well as running real Raspbian (or what ever it’s called now).
My use-case for my Raspberry pi is satisfied with a UART console, Ethernet, and USB. I don’t connect the HDMI outputs to anything unless I absolutely have to. My main use case is just to have a quiet armv8 board for Debian packaging work (day-job has loud (for a small office) armv8 boards I support).
