Does this greeny / pinky screen ring a bell in your expert minds?

#1

I have an android app that plays a video on texture. Everything works fine, but when the video starts to play, only on 1 of my devices (oneplus 6t) out of 5 devices, the screen around the video becomes greeny / pinky. I’m not an opengl expert, but I thought maybe these strange colours coming from nowhere could ring a bell to some of you. Thanks for any help/hint.
