Flashing colors on startup after automatic close on mobile

When attempting to suspend Minecraft and use other apps, it has a tendency to automatically save and close itself, which usually just means you open to the main menu when you go to resume play and must re-enter the world you were playing on. Minor annoyance, but I wouldn't consider it a bug by any means, just mobile being mobile. What is definitely a bug, and I'm not sure on exactly how to reproduce, is sometimes when it does this automatic closing, and you go to resume play, instead of loading straight to the main menu as per usual, it takes on screen-enveloping flat colors that flash from one to another rapidly, frame by frame. This could be very dangerous for people with epileptic sensitivity to flashing lights. I'm pretty sure that the colors which are flashing are the colors of single pixels on blocks, lots of greens, browns, and greys, with occasional other colors like teal, yellow, and red. It does this for a couple minutes before the main menu is finally produced and functions normally. You can stop it by simply closing Minecraft completely and re-opening it, but there's still risk in even the briefest of flashing sequences for people who are sensitive to them.
