aguo1882For me, i just follow this and fix black crush in picture, but i still get black crush in video player, but seems better than before. idk why, Maybe HW overlay issues?
Google it if you don't know. This is a very common issue for the ROG Phone 3.
I fixed the black crush issue by going into Developer options and turning this option on:
Disable HW overlays - Always use GPU for screen compositing
All the weird screen issues went away, Youtube looks normal now and I have yet to experience black crush.
