Created attachment 1013 [details] Client options with "security" as selected tab Our current client option interface doesn't indicate in a clear way which tab is selected. See the attachment. It's possible to highlight the selected tab using "tabs->selection_color();": https://www.fltk.org/doc-1.3/classFl__Tabs.html#Highlighting_The_Selected_Tab We might also consider making the label of the selected tab bold or something along those lines.
This upstream PR would fix this issue: https://github.com/TigerVNC/tigervnc/pull/1410
