Hello,
I have tried the Unreal Match 3 example, and see that if I click settings button to show the menu scroll, the fps is also decrease with 10.
I noticed that the menu scroll have a background.
PS. I am using UE4.16, and my phone is Samsung Galaxy J5 (2016), CPU: Quad-core 1.2 GHz Cortex-A53, GPU: Adreno 306
Thanks.
