Under the titlebar, there is a 1-2px line that seperates the decoration from the window content. There used to at some point (in kde4 I think) an option to hide it. It would be really nice to have it back! Here are some relevant links: https://www.reddit.com/r/kde/comments/5079wd/is_there_a_way_to_remove_this_titlebar_seperator/ https://www.marc.info/?l=kde-commits&m=142141626103679&w=1 Reproducible: Always
Hi, Thanks for reporting. What is the use case for having such an option ? I can understand that one would want to remove it when chosing the same window decoration background color as the window background (which is done automatically already), but I cannot find a reason for doing it in any other case. Is there ? If not, I am afraid this will be a "wontfix" since the separator is seen as a design choice, and because we try to avoid adding to many "corner case" options (they tend to clutter the code, generate bugs and make things less maintainable) Regards, Hugo
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.
Hi, I'm not sure I really understand the problem and the fix, but if 'fixed', I am glad. Closing.
