<div>One thing that you might try is having an extra canvas with a color the same as the GOP patch's background color change vis_size to cover up / hide the stuff you want to "disappear." I don't think you can make canvas have a vis_size of 0 0, but 1 1 with the right background color isn't visible in most cases.</div>

<div>Of course this doesn't work at all if you intend to move things around beyond simple hiding and showing. It can also be very tedious to set up the visible order and the receive symbols of these canvases, but it does seem to be shown with GOP<br>

<br>However, when a gui element is moved away from the gop area (via a "delta" message), it is redrawn outside it.

<br>The viceversa also happens: you move it back to inside the gop area, it is still invisible; as soon as you move the containing object then it becomes visible.<br><br>Obviously a bug. The question however is, can anybody think of an easy workaround?<br>
