Problem Regarding Fullscreen With Forge

[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?

i had the same problem at the start the only way i could acces other windowns was by closing java so then i did a google search and all you need to do is press f11 or on a mac fn and f11 at the same time and then itl make the screen smaller and then u just resize it and its back to normal.

1.12 is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.
