I have a scripts[0] use io[1] command to dump the VOP2 register you can use it dump the register configuration when you meet a display failure,
then send the dump to me, maybe I can figure out something.

Pls see https://pastebin.com/CHmu9s22
I put dumps for following scenarios:
-boot -modetest -s 69@67:1920x1080 -> ok -modetest -P 43@67:1920x1080@NV12 -> green screen
-boot -modetest -s 69@67:1920x1080 -> ok -modetest -P 49@67:1920x1080@NV12 -> ok (but shifted horizontally by about 5% of screen width)
Have you applied the bugfix I shared with you here:
