Created attachment 179470 [details] A Screenshot of the Relevant Application's Window Decorations SUMMARY When a 3rd-party application disables minimisation and maximisation functionality, KWin renders the closure button where the minimisation button should be, and does not render the aforementioned despite reserving space for them. STEPS TO REPRODUCE 1. Visit https://github.com/Mbucari/Libation/actions/runs/13800373941#:~:text=64.6%20MB-,Libation.12.0.3.2%2Dlinux%2Dchardonnay%2Damd64.rpm,-86.6%20MB 2. Download the ".zip" file served by the "Libation.12.0.3.2-linux-chardonnay-amd64.rpm" entry. 3. Extract the ".rpm" file from it (via Ark). 4. Invoke "sudo dnf5 install" with its path. 5. Invoke the Libation GUI. 6. Invoke "Settings". OBSERVED RESULT KWin renders the closure button where the minimisation button should be, because it reserves space for the hidden buttons. EXPECTED RESULT The closure button should render on the right.

Comment on attachment 179470 [details] A Screenshot of the Relevant Application's Window Decorations Albeit tangential, I've since reported https://bugs.kde.org/show_bug.cgi?id=511464#c1 about the inconsistent screenshots. Additionally, I've tried to recently reproduce this using https://github.com/rmcrackan/Libation/releases/download/v12.0.3/Libation.12.0.3-linux-chardonnay-amd64.rpm in https://discussion.fedoraproject.org/t/how-to-create-a-toolbox-in-fedora-38-silverblue-with-a-downgraded-gcc-gcc-12-instead-of-gcc-13/86781/2. However, it dies, and since I have no clue about how an application can decide to not render such buttons, I just can't.
