--- Comment #2 from nikol...@kakouros.net --- Not any important as I can tell. The issue came up with firefox and other apps not written in qt that do not follow kde's color settings. In firefox, I had a blue theme and had applied a blue titlebar through "Special application settings" , choosing a custom color scheme. The seperator was there, although the window and titlebar had the same color. It then crossed my mind to set the window color in the color scheme to the same blue color, even though it wouldn't be used. And that seemed to do the trick. So, solved for my case. -- You are receiving this mail because: You are watching all bug changes.
