Android scene flipped upside down with GIsDumpingMovie = true;

[anonymous_user_a8a1575a]

I put “GIsDumpingMovie = 1;” in FMyGameModule::StartupModoule() to enable offscreen backbuffer.
Everything looks fine with PIE, and iOS.
But Android scene flipped upside down except UMG UI.
What is proper way to enable offscreen backbuffer in android?
