SUMMARY The filename of the open/focused document is missing from the window title (on X11 at least) STEPS TO REPRODUCE 1. Open any .kra file 2. See that version number and exe-name in the window title - but no filename OBSERVED RESULT "4.2.7-beta1 (git e9b2584) : <empty> — Krita" EXPECTED RESULT "4.2.7-beta1 (git e9b2584) : <filename.kra> — Krita" SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 18.04 / backports KDE Plasma Version: 5.12.9 KDE Frameworks Version: 5.47.0 Qt Version: 5.9.5
That's because the filename is shown in the tab if tabs are enabled. It's shown in the titlebar if krita is in subwindow mode with the subwindow maximized. It's not very neat, but Qt internally juggles the titles this way.
