Created attachment 151498 [details] Dialog as it is displayed on Leap 15.4 When opening image editor on Leap 15.4 the dialog for the light settings looks wrong. STEPS TO REPRODUCE 1. Install openSUSE Leap 15.4 with XFCE desktop 2. Install digikam from openSUSE repo and start it 3. Try to edit an iimage OBSERVED RESULT See first screenshot EXPECTED RESULT The percantage sliders should look like in the App Image for digikam 7.7.0 SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUE Leap 15.4 (available in About System) KDE Plasma Version: - KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION Comment from a colleauge that maintains libqt5-qtstyleplugins: "Looks like digikam is missing a progressOpts.state |= QStyle::State_Horizontal." He also said hould mention though that the digikam bug will only have a noticable effect with Qt 6, so with Qt 5 it won't make a difference.
Created attachment 151499 [details] Same dialog, this time in AppImage for digikam 7.7.0
Go to the digiKam setup under Miscellaneous-> and select the Fusion style. Maik

(Fortunately) I'm not a qtstyleplugins maintainer, but I did have a look anyway. We have a downstream (?) patch adding some Qt 6 compatibility to the GTK2 style and that included switching away from the deprecated QStyleOptionProgressBar::orientation to using ::state instead. It looks like digikam only sets the former (implicitly through the constructor) but not th latter. With Qt 6, all styles only use (state & QStyle::State_Horizontal), so it'll probablylook broken with most styles then.
