Fonts turned transparent with black outline. Almost impossible to read.

[Gary Steinman]

All headline fonts on my LG G3 turned transparent with black outline.
Tried everything I know in settings but no cure. Tried to turn off all options in Accessibility. Did not work.
Please help.

Do you have some kind of non-stock theme installed?
Check under:
Settings-> Display-> Home Screen it is under Screen->Theme

what do you mean by non-stock theme ?
I am using the Drupe Application and using it as a Home Screen.
If I change the Home screen to be the LG one, the theme is LG.
I will try to remove the Drupe App. and restart the phone
