2. large windows tended to leave a lot of artifacts behind during movement (the video shows this towards the end).

there is two "modes" to blit on Morphic display - one is just copy directly to Display, and another is to separate form and then draw that form as usual. so, these artefact is not related to OpenGL per se, but mainly to how you make rendered results appear integrated in morphic.

Is there a way to directly draw to the system window using OpenGL so that intermediate software blitting is eliminated?

The integration of 3D and 2D on the squeak desktop (World morph) would be much easier and faster if there weren't so many layers of copying being done, as is the case with my demo video.

If there IS a way, can you create a demo of it,, or explain to me how to create a demo of it?

Thanks, Lawson
