Single buffered GL contexts will do this.  Send a buffer 1 to the gemwin before creating the window.  Then bang the gemhead each frame (metro works well for this).  Sending a bang to the gemwin will clear the window contents.

hello list,

with GEM, is there an equivalent to Jitter's jit.lcd object?

jit.lcd lets you draw lines which stay permanently on the screen in 2d
space, rather than as OpenGL objects, or what have you - it's more like
moving a pen across a surface, you just draw a line and then forget about it.

thanks
