When starting the game on a mobile device, you may notice that after loading the Roblox window and before the splash screen appears, an unloaded scene from the game appears for a moment.
We reproduce this bug at Vivo V17, Sony Xperia XZ3, Poco F1.
In the mean time, maybe you could have the server set the lighting to completely dark, and then have the client set the lighting to normal when it’s loaded?
Thanks for reporting this issue. This issue occurs when the app changes screen resolution (e.g. portrait <==> landscape). There is a single frame when the splashscreen (a core GUI) is rendered only on the left-hand side of the screen, and the right-hand side of the screen displays an empty place with a default skybox.
Unfortunately, this is a minor bug that requires special interactions between rendering and UI which would contradict existing engine architecture. As such, we have decided we won’t be able to fix this issue for now.
