Description

Recently I tried to run Hyprland without any xorg stuff. I disabled Xwayland in the configuration file according to this after I confirmed that most of my daily use applications can run under Wayland not Xwayland.

But after I disabled Xwayland, I found out some QT applications cannot launch and get errors like Gtk-WARNING **: 17:53:34.130: cannot open display:, which is extremely weird because they don't need Xwayland nor Gtk.

I have already set QT_QPA_PLATFORM environment variable and I have confirmed QT applications can run under wayland not Xwayland before I disabled Xwayland.

How to reproduce

Disable Xwayland in the config file
Run some QT applications like qt5ct
