Shotcut

Recentliy I've installed qt5, qt5-webkit and shotcut from the official Slackbuilds. What I've recognized the window of shotcut is too big and to manipulate the windows by the maximize & minimize button does not work. Is there any workaround for these kind of issues?

The weird thing is, I haven't any kind of these issues on Kde.

System: Slackware 14.2
Kernel: 5.2.11
DE: Xfce 4.14
QT5 5.9.8

Shotcut: 18.11.18
