Created attachment 111226 [details] screenshot with missing icon Two issues: 1) https://bugs.kde.org/enter_bug.cgi?product=kate&Bugzilla_restrictlogin=on&GoAheadAndLogIn=Log%20in (above) needs to be updated to accept newer Kate versions. Latest version accepted is 17.12.0. I selected 'git' as I think this might be the right thing for this issue. 2) On both v18.03.70 and v16.08.3 after Edit | Find (or ^F) is selected to display the Find: features, the 'Match case sensitive' icon starts out invisible (when disabled), until hovered over. One clicked it becomes visible, but is simply a gray rectangle with rounded corners and no image in the icon. See attached screen shots. If clicked a 2nd time it again becomes invisible. BTW, once enabled (i.e. the gray box shows up) the searches are in-fact case sensitive, and when disabled searches are case-insensitive as expected. (So the button works, it's just invisible for me. Others have noticed this too. See: https://unix.stackexchange.com/questions/409500/kate-and-case-sensitive-search Debian 9.3 (x86-64), Cinnamon 3.2.7, linux kernel 4.9.0-6-amd64, graphics card AMD RV710/M92, Mobility Radeon HD 4530/4570/545v. I'm not having any similar problems with any of the other icons in Kate, just this one. _______ I'm trying to move from vi to kate, and so thank you very much for kate!

In addition to the above hidden icon, I just noticed a 2nd hidden button to the right of the first, for 'Switch to power search and replace bar'.
And below the pull down with 'In Current File' there are three more hidden icons exposed from hovering, for: "Match Case", "Use Regular Expressions", and "Expand Results"
This is an issue with your icon theme not providing those icons. If they're not present, then the buttons will lack icons, and because these buttons only have borders when you hover the mouse over them, they look invisible without icons.
