Texture artifacts (green/purple/black)

[ap]

Hello

I am trying to play a video on a 3D object.
I am streaming the video (with Android's MediaPlayer) into a texture (through SurfaceTexture and Surface), and then map this texture to a plane. It works, but I get weird artifacts on the borders (looks like a green and black checkerboard and sometimes it blinks green and purple).
It seems to be something with the GPU (PowerVR), but I guess there should be a way to solve this... I am still now sure what it is.

Anyone got that or have any idea how to solve a thing like that?

Thanks

Do you have a screen shot?

Yes.
That's a video "projected" on a plane.

At first I thought maybe it's aspect ratio issue - it wasn't.
Then I thought, maybe something to do with texture wrapping  or texture filtering - neither.
Tried on two devices with PowerVR GPU - same result. Another device with another GPU - worked perfectly.

Maybe it has something to do with video size/aspect ratio compared to the texture's? Maybe the PowerVR video processor can apply certain scales only or something like this...I've no idea, I'm just guessing...
