Created attachment 167594 [details] Plasma 5 with no separator In Plasma 5, when setting the same colour for Window Normal Background and Header Normal Background the same then there is a smooth transition between the Header and the Window. If the colours are different then there is a separator line. In Plasma 6, the separator line remains even if the colour are the same. See screenshots. I don't know if that change was intended or not but I personally find it much nice without a line separator.

Yup, this is the intentional style in Plasma 6, sorry. :)
Hi Nate, Do you know where this change is in the theme code so I could try to change it? I've tried to get used to it but it is bothering me. Many thanks, as always.
