GUI, pause screen and entities disappear

I know that this is a duplicate but you really need to fix this. I am really unlucky because on the original report, a mod said that this bug still works on one device, which I PLAY ON. Anyways as the mod said entering a LAN world on the device I use will cause every entity, GUI (including inventory and d-pad) and pause screen disappear at any possible time. I tried closing then going back and it worked but now every texture is some sort of epileptic. I am upset that the bug is to this day.
