I'm still on 8.1.2 (can't update!) and have the following problem:

Whenever I don't use Swype for more than 5 minutes, the keyboard does not pop up entirely.
That means the bottom row including the space bar is invisible. This is particularly annoying as I can't change languages anymore or press space!

I can usually close the app and reload it and everything works fine. Still it is very annoying as it happens almost all the time.

Could this be fixed?
