Problem Regarding Fullscreen With Forge in Support & Bug Reports Posted November 17, 2019 · Edited November 17, 2019 by n o v a Hello, I have an issue with Forge 1.12.2 (newest version); when I start up Minecraft it is a normal-sized screen, but then it goes into fullscreen and I'm left with a tiny screen in the bottom left-hand corner of my laptop's screen and the rest of the screen is a colour (corresponding to the time of day in the game, weirdly enough). I found a similar post about this problem from a while back but it seems as if no one's heard of this let alone knows how to fix it. Minecraft 1.14.1 is fine and loads up in a normal fullscreen, it is only when I use Forge that this happens. I am using a Macbook Pro if that's necessary information. Help?
