since 2.2.3 I noticed this bug:
When my phone (SGS4 with CM13) switches from mobile data to wifi data and vice versa, Swype keyboard closes and I have to reopen it again by pressing some input trigger (tap into a text field etc.)
This is annoying because when writing something all is gone and I have to restart again. I have often this change of network from mobile and wifi or wifi to mobile so this make this bug happen often.

I didn't check if it happens if I don't use at all any internet use of Swype because I often use Dragon and need that internet data for Swype.
