I was mistaken in the sense that starting calibre with XDG_CURRENT_DESKTOP= does not reset the environment variable so calibre was still using XDG_CURRENT_DESKTOP=XFCE. Sorry about that. Fortunately, you tried another value as well and found that the problem goes away if you use some other value, such as "KDE" (another random string will be fine too, as long as it doesn't make Qt 5 use GTK3). > Does this mean that we don't quite have the infrastructure in place for > this package XFCE? Personally, I don't think that is the problem. Rather, I think that there's a bug somewhere, either in Qt 5 or GTK3 (I'm betting on Qt 5). As you know from my first mail, I ran into this problem myself as well. I'm very interested in fixing the problem but not sure when I'll be able to make time to look into it more deeply. When I get to it, the first thing I want to look at is src/plugins/platformthemes/gtk3/qgtk3dialoghelpers.cpp of the qtbase source code. > At least now I get to add my recent acquisitions, which is good. That's good to hear. Best regards, Caspar Schutijser
