Bugs iPhone Jailbreak

Have You Seen This Weird iPhone Keyboard Bug Before?

This is not the first time that happens while in landscape mode. The screen rotates fine, the keyboard looks fine, but for some reason when I press a key, it appears sideways. I have no idea what it’s from so I was wondering if you guys had seen that before.
I do use the jailbreak app called ShowCase but I remember having this issue before installing the tweak. It’s not a big deal, but I’d just like to figure out what’s wrong…
Let us know if you’ve seen this before and if you know what’s causing this.
