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. Sascha ---------------------------------8<-------------------------------
