I do have this, too, but a screenshot doesn’t show this properly because it doesn’t really have the rounded edges. But if you watch this screenshot on an FP5 in fullscreen mode you’ll see the first letter disappear in the edge:
Fairphone support asked me to try a factory reset and added that this would be necessary anyway if the phone would have to be sent to the repair center… I’m pretty sure this is a simple cosmetic bug, nothing for the repair center. Looks like the software doesn’t know exactly where the rounded corners kick in.
if you don’t need always visible operator name in left of status bar, then:
Settings/Display/NetworkName=Off
(still is show in right before NFC/Network icons, when double pull down Notification)
