[DEV REQUIRED] Talkback suspend feature killing touch response topic

As the above really.

Can ANYONE help me get to the bottom of this?

This massive bug is on every CM11 / AOSP ROM for C6903.

1) Enable Talkback in accessibility

2) Double tap home to get you out of the accessibility screen (or go anywhere else)

3) Draw an L gesture (down and right without removing your finger)

4) A Talkback options screen should come up. Move from the centre to the top left to suspend Talkback

5) Now Talkback is suspended, try un-suspending / re-enabling from Notification bar (pull down and Press Talkback suspended)

6) Now you will find the screen is completely unresponsive and will eventually crash and reboot

This is the MASSIVE bug!

7) Go back to accessibility and disable Talkback to return your device back to normal.

Logcats haven`t shown up any issue. Tried different kernels, different ROMS, all with same result. (This isn`t a handset issue)

Can anyone PLEASE PLEASE HELP?
