[digiKam-users] Wrong overlay position

DK 5.9.0 appimage on Manjaro with XFCE

As you can see from the screen capture, when I hover the mouse over
the image, the top part of the overlay is above the screen and I can't
see it.

Now it's not all the time. When I open DK, no problem, but after a
while of writing my captions, tags, labels... this is what happens.

Is this a bug, a setting or an XFCE setting?
