That's fixed now for 11.2.1 and 11.3.0.
Apparently draw text+translucency was never tested. I'll change the
documentation to match.
draw text1 {3 4 5} "some text"
will display a simple text message (not multiline; just colored to
contrast with the background) next to the first vertex of a draw object.
This text will appear at all times if the default "set drawHover OFF" is
in effect, even if the draw object itself is invisible due to setting
its color to "translucent 1". If one has set drawHover ON, then the text
will only appear when the user hovers over one of the points associated
with the draw object.
If more complex, colored, or translucent text is desired, use ECHO instead:
set echo myecho {3 4 5}
echo "some | more complex | text"
color echo translucent white
