1-Go to Browse -> People 2-Click on 'Scan collection for faces' button 3-Click on 'Options>>' button When you click on Advanced tab, others tabs go down and when you return to Albums tab or go to Parameters tab, all tabs go up. Reproducible: Always Expected Results: All tabs should not move.
This layout problem is due to QLabel named "cpuExplanation" plugged in Advanced page with properties setWordWrap enabled. This label take a priority in KTabWidget to resize it automatically when Advanced tab is selected. Sound like a problem in Qt (i tried to use QTabWidget instead). Code relevant is here : https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/entry/utilities/facemanagement/facescandialog.cpp#L410 I reassing it... Gilles Caulier
This problem was fixed in digiKam 5.2.0, but I don't know if this affects other software. Using Plasma 5.7.5, Frameworks 5.26 and Qt 5.7.0.
It's fixed in digiKam since the port to Qt5. Gilles Caulier
