[SOLVED] weird screen bug on Honor play?

[Sibbe_]

idk what this is but ive was whatsapping with someone for quite some time, like a view hours no stop, and suddenly his/her name stayed in every app! like very dimm it was still there its hard to explain but i can't make apicture of it but it's really weird... I'm trying to revert it by putting my screen on full brightness and then just black for like an hour but i don't know if it'll work and i really want it to back because it look insanely annoying, Oh yeah i must add that in some colours you cant see it, if there is black displayed oyou cant see it and if its blue (havent checked other colours)
my question,
will it stay like this?
can i fix this?
how can i fix this?

It's possibly an operating system bug or the phone is not powerful enough to keep up.

Restarting will likely fix it.

It's not a hardware problem hopefully.
