My minecraft suddenly one day went into a weird split screen that makes doing anything difficult. I had recently tried to download a mod pack that didn't work for unknown reasons. I deleted the mod pack and my minecraft. Then I re-downloaded Minecraft twice to no effect. I don't know what to do, please help!
If the sections of a normal screen in minecraft look like 1 2 3 ... Mine looks like 2 3 / 1
