QT 似乎在 gnome 下扩展了两倍。
当我从 gnome 启动 QT 应用程序时，图标很大。当我qt5ct从终端开始时，缩放是固定的，图标是正常大小的。
我努力了：
- 将
QT_SCALE_FACTOR环境设置为 1。 - 将缩放设置为 1 英寸
KDE System Settings
[编辑] QT_SCALE_FACTOR=0.5.\profile 中的设置似乎将所有内容缩小了一半，但将其设置为任何其他值都会恢复为大图标。
gnome-control-center不会启动，当我尝试从我看到的终端开始时：
Failed to register: Timeout was reached
我已经尝试gnome-control-center通过重新安装pacman。这没有做任何改变。
我从 启用了scale-monitor-framebuffer实验功能dconf，禁用它并没有什么不同。
我从 arch 存储库继续gnome 3.28运行。wayland
我journalctl -b | grep gnome-control-center的是：
