[MCPE-1899] (Pocket edition) standing on a cacti while looking at the armor tab makes some of the GUI red

When you stand on a cacti, or just simply touching it and you look at your armor tab some of the GUI is red

Linked issues

i don't think this is a bug. I think this is the intent in case you were being killed (mob,pvp ect) while your inventory was open.

No it's only with cactuses if someone is punching you to death none of the GUI turns red

is this on all pocket edition games? is the free or paid?
