Spacebar does not work and may be related to the screen glitching out while in the chat menu.

I was playing on a minecraft pocket edition server and I tried to login to the server with /login (my password) and it wasn't working. I then tried other servers that required the same input and it wasn't working. I noticed the glitch (2nd image) and assumed that that was the case because I couldn't see the chat while typing only. The last thing I tried was typing in a single player world (1st image) and I realized that even thought I was pressing the spacebar, it wasn't inputing a space between words. I checked to see if it was my device, but when I would text it worked perfectly fine.

What I was trying to do: Type into chat and put a space between words or characters.

What actually happened: No space was inputed between words or characters.

Steps to repeat:
1.Tap on chat icon (either singleplayer or multiplayer)
2.A glitch should appear where you can't see what you are typing; ignore it
3.Type a sentence with spaces between words using the spacebar
4.Tap return/enter
5.Exit the chat menu by tapping the "Back" button
6.Notice that there are no spaces between the words in the sentence you just created
