This only sets the overlay, but how did you get something on the screen
initially?

I did with "modetest -s 69@67:1920x1080 -d" and with this it works as
expected, I can't reproduce any green screen issue here.

I found another problem though which might or might not be related with
your issue. I saw that the overlay is not exactly centered as it ought
to be. This goes down to wrong delay settings for the overlay, the
following patch fixes this.
