Hello guys! Im using the official minecraft launcher, and decided to give Beta 1.7.3 a try for that nostalgic feeling of playing it for the first time on my grandmother's ancient PC. However, even when full screen I get what you can see in the image above, and I cant find any settings to change the resolution.

Keep in mind, Im on a weird setup. Im on Arch Linux with bspwm and 2 monitors.

If I press F11 while fullscreen it cycles through several modes and eventually gets to one where the game looks right as it should, but unfortunately that disables my second monitor and I need to restart bspwm to get everything as it should be (otherwise it just duplicates the first monitor to the second one).

I read in some forum threads that where might be some java launch arguments that can set the resolution, but Im not sure how to do any of that from the MC launcher.

Any help is appreciated!
