Some icons are missing. Look at attached screenshot (toolbars and settings dialog). Additionally the font used is wrong (I have different font in systemsettings for UI). Reproducible: Always
Created attachment 94583 [details] Missing icons (and font - it should be Trebuchet MS)
Something strange happens. When I run gwenview from terminal, it seems to follow systemsettings regarding widget style, fonts, all icons are shown correctly. However when clicking on an image in Dolphin and running Gwenview from there… the bug reproduces.
Doesn't reproduce since my last system upgrade. The only KDE-related difference I can spot in upgrade log is change of Qt version from 5.5.0 to 5.5.1. Maybe it was the problem.
Thanks for the update; changing status.
