Appears some Android OpenGL drivers are not preserving the texture filtering when changing render contexts. Added saving and restoring it in context cases.
1. Make a project for Android
2. Add an mp4 to Content/movies
3. Hook up the movie playback
4. Launch on device and get close to a movie and look for point sampling instead of bilinear filtering
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-41565 in the post.
