In vbox, I cant adjust the screen size or resolution without KDE putting it back to normal screen resolution. This problem happens with all KDE platforms, and it does not happen with XFCE Manjaro. This was a fresh installation. I have tried using Alt+Shift+12, but that also doesn’t work. I would be happy to give any other information needed. Xrandr also doesn’t work. Whenever I try to adjust the screen resolution, it goes back to its original size and a notification comes up that says, " Desktop effects have been suspended by another application. You can resume using the ‘Alt+Shift+F12’ shortcut."
