Intermittently “no signal” on TV when switching to Vero 4k+ on Kodi v19.1

If this can be seen as the same issue I reported
Vero 4k+ and loss of display after a long idle time
then I still have to use my custom Harmony remote action “Kodi reboot” occasionally with the latest December 19.3 version.
By occasionally, I am measuring it in weeks rather than days: so perhaps every 2 weeks rather than after 2 days.
Symptoms are the same: switch my TV setup over to the Vero input, and the display stays blank and I can’t “wake it up”.
Harmony reboot option works every time, and I sometimes see the shutdown text before the reboot but not always.
(GUI is still set to 1080p)
