• I have searched the issue tracker and did not find an issue describing my crash.

Minecraft version.

1.18.1

Sodium Extra version.

0.3.7

Sodium version.

0.4.0 alpha 5

What happened?

I was attempting to use Sodium Extra to downscale my resolution in fullscreen. On my 16:10 laptop, i was able to set a custom fullscreen resolution just fine. When I tried to set a custom resolution on my 21:9 monitor, the game crashed instantly and kept crashing on startup until I removed Sodium Extra from my mods folder and restarted the game on my laptop screen.
