BackGround: My Game prefers to use DX12 as default RHI, thus we have to do “PSO Cache”. We didn’t do any extra setting, so the game will load all of the PSO content when launching game, and more than 70,000 shaders would be precompiled. The loading and precompiling process takes a lot of time, so StartMovie was set “MT_Looped” mode and won’t stop until loading complete. Then GameDefaultMap will be load and one widget would shown with shaders being compiled.
Issue: Some players encountered a long time Black Screen after StartMovie, we want know why and how to fix it. Please provide some help.
