Here is Bleachbit, a GTK3-based disk cleanup utility. It is a blurry mess and GTK3 Window headers are completely out of style and behavior with Windows.

The problem is they half-ass it. Qt only does it with QML. Qt Widgets is half-half and it is a mess.

Overall these do not invalidate my point though. If you want a truly cross-platform application GUI, you need to rewrite the GUI for each OS. Or you give up and write one GUI that's running on its own platform.

Indeed, Google employs some of the smartest software developers and ones with really niche skills like Behdad Esfahbod who created the best or the second best font rendering library out there. However, Qt has a company behind (a very very incompetent one, not just the library but operating a business). I have seen many commercial libraries too, they are all various shades of terrible.
