disappearing text: typing bug

So, I've been having this issue of text disappearing when I'm writing a post or text message. It usually does it when the word would go to the next line on the message box, only when this happens part of the word(s) is(are) missing or split between the two lines and letters are. I can't highlight it with the cursor and have to delete the message and start over to fix it because it seems the whole line is bugged or something . I hope I am doing a enough to describe this and people understand what I mean.
I'm using perfect keyboard.

Could this be a perfect keyboard problem? Android 2. 3. 4? Prudery? Is anyone else experiencing this or something similar?

 

yeah I will take a pic. It hasn't done this in a day but I will try to capture it. Sorry, I know I wasn't being clear, but it is just difficult to describe. I should have a pic up by tonight. Thanks for replying!
