What do you mean by window hints?

ghost commented 6 years ago

They're part of the Free Desktop spec (XDG) for Linux GUI apps. Most apps have them as they're typically included by default in GTK, QT, and similar toolkits.

I'm not sure if libui implements Window Manager Hints, but both #6336 and this issue seem to do with ICCCM issues.
