Title screen gamma set to 1500% automatically

[generic60]

Not a crash - the game runs perfectly fine. However, there's a visual bug on the title screen where the gamma just cranks itself up for no reason. I've tried reinstalling but nothing's happened. I don't have any FullBright-esque mods, so I'm not sure what could be causing it. 

Game version is 1.18.2

Forge version is 40.2.21
