When I run this on a TV that is used in place of a monitor, I get a full window instead of the specified geometry.
That switch used to work with my Acer monitor.
gxmessage -fg red -font 'sans 50' -timeout 3 -geometry 100x100 'testing 123'
Using any 2 values for geometry always results in a full window being displayed instead of one that is 100x100.
Is there a workaround?
