Package: qt5-gtk-platformtheme Version: version 5.15.2+dfsg-14 I just installed this to see whether or not it would help enable an in- development Qt app adapt to the Gnome system theme. (Please consider packaging qgnomeplatform from [1]).
I noticed that there seems to be an issue with HiDPI with this package, with various GUI text components being too large in that app with this package installed. [1]: https://github.com/FedoraQt/QGnomePlatform
