I have an issue similar to this one reported in this linux forum : https://forum.manjaro.org/t/windows-not-sizing-properly/67171/30
Manjaro Linux have moved to the GTK3 version of XFCE. I took the latest version but now I see that when I maximise windows the bottom of the window goes past the panel at the bottom. It's an issue when using IDEs such as IntelliJ because it has buttons at the bottom of the IDE which are no longer visible because they are hidden behind the bottom XFCE panel.
This seems to be fixed with the latest release from Manjaro which contained the latest XFCE patches.
