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,<br><br>with GEM, is there an equivalent to Jitter&#39;s jit.lcd object?<br><br>jit.lcd lets you draw lines which stay permanently on the screen in 2d<br>space, rather than as OpenGL objects, or what have you - it&#39;s more like
<br>moving a pen across a surface, you just draw a line and then forget about it.<br><br>thanks<br>d<br><font color="#888888">--<br>damian stewart | +351 967 797 263 | <a href="mailto:damian@frey.co.nz">damian@frey.co.nz</a>
