OS 11.2 HDMI is still flaky

Not really a question -- more of a data point:


My Mac mini M1 HDMI to DVI output is still a bit flaky even after the OS 11.2 update. Twice now, I've experienced a monitor "snow crash" on wake-from-sleep -- nothing but random pixels on screen. Putting the computer back to sleep then waking it again restored HDMI functionality.


This has happened only after the computer had been idle overnight. It hasn't occurred with normal wake-sleep-wake activity throughout the day and it hasn't yet risen to the level of annoyance that would make me revert to Thunderbolt to DVI output.


(The monitor, a ten year old HP 2010i with DVI and VGA inputs, always worked well with my 2010 MacBook Pro and OS 10.13.6)
