Green artefacts or whole green screen in videos (introductory ads) of games in PPSSPP (issue on Amlogic tv box - coreelec/linux based)

[atirage21]

Game or games this happens in

In all games with introductory short videos.

What area of the game / PPSSPP

Many times was freezed device for playing introductory ads (bug in entry part of game, but after game was ok. Only videos in game are impacted). I was successful by logging of errors thanks to early pushing button in time of introductory ads playing.

What should happen
