Regarding additional information about the issue UE-22367, this issue refers to the inability to render transparency on 3D widgets when used on a mobile device. As for the resolution of the issue UE-20777, there is no current time frame in place for the implementation of a solution for this issue. I hope this information helps. Make it a great day
