I’ve encountered this issue a few times and think it is linked to the automatic switch to power saving mode.
If during writing an answer, e.g. for WhatsApp, via the push up ( so not in the app itself) the power saving mode is turned on the text field is [always/sometimes?] duplicated.
That is, I have a ligher and darker text field beside each other (50% of the original size) that are synced. All text I write is shown and updated in both text fields.
Sounds like a bug.
Best thing to do is to report this to official Fairphone support (click contactsupport for more info) as they don’t necessarily read all the forum posts.
Make it clear that this occurs when writing a quick reply in the notification panel. I’m not sure that the expression “push up” will be clear to everyone.
And welcome to the community forum 
hi @Enthusiast
welcome to the community form.
I don’t think i have seen something like that before.
Can you make a screenshot of the issue when it happens again?
don’t forget to hide all personal data and information on the screenshot before uploading it to this form.
have you already tried to change the battery usage settings of whatsapp?
open your app menu → long press on WhatsApp → App information → battery usage of app → set to unlimited.
which keyboard do you use on your phone?
the default one?
the second text bar may be part of the keyboard.
greetings
Tom
