After upgrading to iOS8, when I add subtasks under a task the screen clears and I can't see what I'm typing. Steps to reproduce:
- create new task
- go to add subtask by putting cursor in Subtask field
- start typing.
The screen clears up - can't see the data entry field.
- complete typing the subtask (even though can't read it) and press Enter
Subtask still missing.
- Switch to different task, and then switch back
Subtask appears!
- repeat step 2 - same thing happens.

Could this please be addressed urgently as it is seriously damaging my workflow, as I use subtasks extensively.
Note - I tried to add screenshots from the iPad but this site won't allow ipad screenshots?? could you also remove this restriction, it would problem reporting easier and clearer for you!
