> The resolution of the problem in DrGeo is as follows:
> 1. In drgeo.sh, add exec options '-compositioninput' like
> exec "$VM/pharo" \
> -plugins "$VM" \
> -encoding utf-8 \
> -vm-display-X11 \
> -compositioninput \
> "$image"
>
> 2. Change recordPendingKeys(void) in vm-display-X11/sqUnixX11.c as
> follows and
> rebuild vm-display-X11.
