Parts of username is displayed just to the left of the user selection box
The ComboBox that makes up the user selection seems to display the username, in addition to the icon. In most cases I guess this does not show up due to the user selection button displaying over the text, but in my case I can see parts of the first character in my username (a). See the attached screenshot:
My resolution is 2560x1440. Plasma 5.18-2, SDDM 0.18.1-2 and version 1.6 of Sugar Candy.
This can be fixed by adding
displayText: "" to this ComboBox.
Thank you for this nice theme :-)
