When you are playing solo or split screen, and the keyboard gets disconnected from the xbox, the mouse is still present and the screen flickers when inside of menus.

When in:
-The Home Screen
-Options
-Crafting Interface
-Anything that pops up (Stores in Servers, etc.)
It will flicker, or freeze (Pressing home will show the current screen, then going back will freeze it again,)

When In:
-Gameplay
It will run fine, the mouse cursor will stay present though where ever it was last left.

TO FIX:
1. Start minecraft with the mouse plugged in.
2. Go through the options, and if it glitches reinstall minecraft and start from #1.
3. Close minecraft, and when at the home screen unplug your keyboard and mouse.
**4. If all else fails, a hard reset might fix the problem temporarily.

This issue, has been with me and I resolved it, so no pictures will be uploaded because it took 3 days to fix it, and I don't want to either have it glitched permanently, or stuck like that.
