(1) In regard to the "red lines" issue when starting a new game. I've read that changing the backend from OpenGL to Vulkan and back again could fix it. The way I fixed it, because I am playing it on a Samsung Galaxy S5 (yes, you heard right; more about that later :-) ) and don't have the Vulkan backend, is by having a save state at the main menu, and constantly reloading it until the game starts without the red lines. Once you achieve a good startup without the red lines, save state again, and then continue everything from that save state, including new save states. You can also try constantly exiting a game and restarting a new one, though I'm not sure if that would work. Maybe constantly resetting and starting the game would also work.
