A question about Qt/LXQT.

When starting LXQT with startlxqt LXQT crashes giving a core dump and
showing in the systemd logs the message
'Unable to find an X11 visual which matches EGL config'

The setup is connecting from a Windows 10 client to a system running Arch Linux using (x)rdp.

On the Arch Linux system lxqt is started from ~/.xinitrc.
But a (x)rdp session is not created because of the above error.

Changing 'exec startlxqt' into 'exec xterm' in ~/.xinitrc does indeed create a xrdp session but of course with just a xterm window. Calling any Qt program in this terminal window leads to a core dump and that message
'Unable to find an X11 visual which matches EGL config'
suggesting it's caused by Qt.

Last weekend 6 Januari I did a pacman -Syu and Qt was updated to version 5.10.0.

Does anybody have an idea what change in Qt may be causing this error ?
